The second surah revealed to the Prophet, immediately after the first revelation, contains the command *And purify your garments* (Al-Muddathir 74:4). The Qur'an says *Indeed, Allah loves those who repent, and He loves those who purify themselves* (Al-Baqarah 2:222). Cleanliness in Islam has two wings — outer (body, clothing, environment) and inner (heart, intention, character); the believer's purification is complete only with both. Cleanliness in Islam is not a recommendation for hygiene; it is a founding principle of existence. Among the first commands revealed to the Prophet, right after the first revelation itself, is *"And purify your garments."* This sermon explores how the Qur'an treats cleanliness in two essential dimensions — outer and inner — how the Prophet placed it as one of the two halves of faith, and how the believer is to live this awareness in daily life. ## The Command That Came With the First Revelation The first revelation came to the Prophet in the cave of Hira. The angel Jibril said *"Read!"* and taught the Prophet the first five verses of Surah Al-Alaq: > ٱقۡرَأۡ بِٱسۡمِ رَبِّكَ ٱلَّذِي خَلَقَ. خَلَقَ ٱلۡإِنسَٰنَ مِنۡ عَلَقٍ. ٱقۡرَأۡ وَرَبُّكَ ٱلۡأَكۡرَمُ. ٱلَّذِي عَلَّمَ بِٱلۡقَلَمِ. عَلَّمَ ٱلۡإِنسَٰنَ مَا لَمۡ يَعۡلَمۡ > Read in the name of your Lord who created. He created the human being from a clinging substance. Read — and your Lord is the most generous; the One who taught by the pen, who taught the human being what they did not know. Surah Al-Alaq 96:1-5 After the first revelation there was a pause. Then the Prophet, hearing a sound from the heavens, looked up and saw the angel he had met at Hira. He returned home in fear and said, *"Cover me, cover me!"* They covered him. At that moment, the opening five verses of Surah Al-Muddathir came down: > يَٰٓأَيُّهَا ٱلۡمُدَّثِّرُ. قُمۡ فَأَنذِرۡ. وَرَبَّكَ فَكَبِّرۡ. وَثِيَابَكَ فَطَهِّرۡ. وَٱلرُّجۡزَ فَٱهۡجُرۡ > O you who covers himself, arise and warn. Magnify your Lord. And purify your garments. And keep away from filth. Surah Al-Muddathir 74:1-5 At the very head of the prophetic mission stands a five-part directive: *rise, warn, magnify your Lord, **purify your garments**, **keep away from filth.*** The first of the last two is the herald of outer cleanliness; the second is the opening of inner cleanliness. Cleanliness is built into the prophetic mission itself. ## Allah Loves Those Who Purify Themselves The Qur'an expresses its love for purity in explicit terms: > إِنَّ ٱللَّهَ يُحِبُّ ٱلتَّوَّٰبِينَ وَيُحِبُّ ٱلۡمُتَطَهِّرِينَ > Indeed, Allah loves those who repent, and He loves those who purify themselves. Surah Al-Baqarah 2:222 That the verse pairs repentance and purification is significant. Repentance is inner cleansing; the inside, stained by sin, is washed by repentance. Just as the body and the garment are purified, so the soul too has a purification that earns Allah's love. Another verse, praising the believers of the Quba Mosque, echoes the same love: > فِيهِ رِجَالࣱ يُحِبُّونَ أَن يَتَطَهَّرُواْۚ وَٱللَّهُ يُحِبُّ ٱلۡمُطَّهِّرِينَ > Within it are men who love to purify themselves; and Allah loves those who purify themselves. Surah At-Tawbah 9:108 ## "Cleanliness Is Half of Faith" The Prophet placed cleanliness inside the religion with one of his most striking sentences: > Cleanliness is half of faith. Half of faith. This single sentence summarises the place of cleanliness in Islam in a way nothing else does. It is why the validity of the highest act of worship — the prayer — requires the body, the garment, and the place of prayer all to be clean. Allah Himself commands ablution before standing in prayer: > يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِذَا قُمۡتُمۡ إِلَى ٱلصَّلَوٰةِ فَٱغۡسِلُواْ وُجُوهَكُمۡ وَأَيۡدِيَكُمۡ إِلَى ٱلۡمَرَافِقِ وَٱمۡسَحُواْ بِرُءُوسِكُمۡ وَأَرۡجُلَكُمۡ إِلَى ٱلۡكَعۡبَيۡنِ > O you who believe, when you rise to prayer, wash your faces and your hands to the elbows, wipe over your heads, and wash your feet to the ankles. Surah Al-Ma'idah 5:6 Five times a day, before standing in the presence of his Lord, the believer washes. This raises bodily cleanliness from a routine habit to a gate that opens before every act of worship. ## Two Wings: Inner Cleanliness and Outer Cleanliness Cleanliness has two wings — one inner and one outer. The believer needs both to fly. ## Inner Cleanliness Inner cleanliness is the purification of the heart from ill thoughts and feelings, and of the limbs from sin. Cleanliness of the heart precedes every other form of cleanliness. When we say *"so-and-so is a clean person,"* the first thing that comes to mind is the purity of their feelings, the way their heart is filled with love and goodwill toward people. The Prophet taught that deeds are weighed by intention, and the seat of intention is the heart. Allah judges people by what is in their hearts: > Allah does not look at your bodies or your appearances, but He looks at your hearts and your deeds. ### The Hadith of the Morsel of Flesh The importance of the heart is set out in another hadith: > Truly, in the body there is a morsel of flesh: when it is sound, the whole body is sound; when it is corrupted, the whole body is corrupted. That morsel is the heart. When the heart is corrupted, the tongue, the eye, the hand all follow it. When the heart is set right, the limbs follow it too. Inner cleanliness comes before bodily cleanliness for this reason. ### A Reply to "My Heart Is Clean" Some people, when they neglect their religious duties, defend themselves by saying *"My heart is clean."* They overlook a basic fact: **whatever is in a vessel is what pours out of it.** Clear water does not pour from a vessel of muddy water. The cleanliness of a person whose heart is genuinely clean shows up in all their limbs. The one whose tongue, hand, or eye harms others has not earned the right to say *"my heart is clean."* The Prophet said: > A servant's faith is not upright until his heart is upright. His heart is not upright until his tongue is upright. And a person does not enter the Garden until his neighbour is safe from his harm. ### Sin Stains the Heart — The Verse of "Ran" Each sin leaves a black mark on the heart. The Prophet explains: > When the servant commits a sin, a black mark appears on his heart. If he repents and seeks forgiveness, his heart is cleansed and shines. If he returns to sin, the mark grows; until it overwhelms his heart. That is the *ran* of which Allah speaks in His verse: *"No! Rather, the stain of what they were earning has covered their hearts"* (Al-Mutaffifin 83:14). > كَلَّاۖ بَلۡۜ رَانَ عَلَىٰ قُلُوبِهِم مَّا كَانُواْ يَكۡسِبُونَ > No! Rather, the stain of what they were earning has covered their hearts. Surah Al-Mutaffifin 83:14 Only repentance can clean this stain. The one who feels remorse for their sin and asks Allah for forgiveness finds their darkened heart returning to light. ### A Pure Heart — The Only Currency on the Day of Resurrection On the Day of Resurrection neither wealth nor children avail. The only thing that helps, in the words of Prophet Ibrahim's prayer in the Qur'an, is this: > يَوۡمَ لَا يَنفَعُ مَالࣱ وَلَا بَنُونَ. إِلَّا مَنۡ أَتَى ٱللَّهَ بِقَلۡبࣲ سَلِيمࣲ > The day when neither wealth nor children will be of benefit — except for one who comes to Allah with a sound heart. Surah Ash-Shu'ara 26:88-89 ### Zakat as Inner Cleanliness Zakat too, one of the five pillars of Islam, is a form of inner cleansing. Zakat is the right of the poor within one's wealth, and at the same time, it is a stain on the wealth that has not yet been removed. The wealth-holder's own heart, meanwhile, is darkened by miserliness. The mark on the wealth and the dust on the heart are removed only by zakat: > خُذۡ مِنۡ أَمۡوَٰلِهِمۡ صَدَقَةࣰ تُطَهِّرُهُمۡ وَتُزَكِّيهِم بِهَا > Take from their wealth a charity by which you purify them and cause them to grow. Surah At-Tawbah 9:103 ## Outer Cleanliness Outer cleanliness is the believer's care of the body, clothing, dwelling, and surroundings — keeping them free of every form of dirt and filth, and avoiding any sight that may discomfort others. As in every matter, our example here is the Prophet. ### Body and Clothing The Prophet was always careful with cleanliness and well-kept appearance. Abu al-Ahwas (may Allah be pleased with him) narrates: > I came to the Prophet in shabby clothes. Seeing me in that state he asked: "Do you have wealth?" — "Yes." — "What kind of wealth?" — "Camels, sheep, horses, servants." The Prophet said: "Then since Allah has given you wealth, let Allah's blessing and bounty be seen on you." Jabir (may Allah be pleased with him) narrates: *"The Prophet saw a man whose hair was disordered, and said: 'Could this man not find something to arrange his hair with?' He saw a man with dirty clothes, and said: 'Could this man not find water to wash his clothes?'"* A'isha (may Allah be pleased with her) reports: When the people from the outskirts of Medina came to the Friday prayer, the woollen clothes on their backs were dusty, and the smell of sweat rose from their bodies. The Prophet was discomforted and said: *"If only you would bathe today."* ### Dental Cleanliness — The Miswak The Prophet placed great emphasis on the cleanliness of the teeth. A'isha was asked, *"What was the first thing the Prophet did when he entered the house?"* She replied, *"The miswak."* The Prophet said: > The miswak cleanses the mouth and pleases the Lord. In another hadith, on seeing people who had not cleaned their teeth, he said: *"What is the matter with you that you come to me with your teeth yellow? Use the miswak!"* ### The Five Acts of Fitrah There are five practices of natural disposition that every human is expected to maintain. The Prophet said: > Five things are of the *fitrah*: circumcision, removing the hair below the navel, removing hair from the armpits, trimming the nails, and shortening the moustache. Anas (may Allah be pleased with him) says: *"A limit was set for us — that we should not leave these things for more than forty nights."* These acts of cleanliness are to be performed when needed, and not deferred past forty days. ### Environmental Cleanliness The Prophet's warnings against polluting the environment are sharp: > Guard yourselves against the two things that cause people to curse: relieving oneself on the people's paths or in their shade. The Prophet's own mosque was regularly swept and cleaned. A woman named Umm Mihjan used to sweep the Prophet's mosque. When she died and the Prophet had not been told, he asked after her. They said she had passed away. He then went to her grave and made du'a — a sign of how greatly Allah valued the service of cleanliness she had given to the mosque. ## Stories — The Living Picture of Cleanliness ### The Command That Came Right After the First Revelation The scene we described earlier is the key to understanding the Islamic conception of cleanliness. Very soon after the Prophet's first revelation in the cave of Hira, Surah Al-Muddathir was revealed. At the very head of the prophetic mission these commands were given: *Arise and warn. Magnify your Lord. **And purify your garments. And keep away from filth.*** In the very first days of the message, both outer (garments) and inner (avoiding filth) cleanliness were commanded in the same passage. This shows that cleanliness is not a rule added later — it is one of the founding principles of the religion. ### The First Project After the Migration — The Quba Mosque When the Prophet migrated from Mecca to Medina, his first task was to build the Mosque of Quba. The Companions who participated in its construction and later formed its distinguished congregation were praised by the Qur'an for their attention to cleanliness: > Indeed, a mosque founded on righteousness from the first day is more worthy of your standing in it. Within it are men who love to purify themselves; and Allah loves those who purify themselves. Surah At-Tawbah 9:108 The episode of the migration ends with the verse of *"men who love to purify themselves."* The congregation of the very first building constructed in Medina entered the Qur'an under the title *"those who love to purify themselves."* ### The Hadith of the Pure and the Clean Names of Allah The Prophet bound cleanliness to the names of Allah Himself: > Allah is pure (Tayyib) and loves what is pure; clean and loves cleanliness; generous (Karim) and loves generosity; bountiful (Jawad) and loves bountifulness. Therefore, clean your surroundings. The hadith binds environmental cleanliness to Allah's names. *At-Tayyib* (the Pure), *Al-Karim* (the Generous), *Al-Jawad* (the Bountiful) — these names remind the believer to keep clean not only themselves but everything around them. > In modern life, environmental cleanliness is not only the cleanliness of one's home. Not polluting the air, the water, and natural spaces is included in the scope of this hadith. *"Clean your surroundings"* must be lived as the believer not dropping litter, not throwing a cigarette out of a window, and treating shared spaces with the same care as their own home. ## Putting Cleanliness Into Practice With VAAZ The [99 Beautiful Names of Allah collection](https://getvaaz.com/en/asma-al-husna) in the [VAAZ app](https://getvaaz.com/en) features *Al-Quddus* (the Most Holy, free from every imperfection), *At-Tayyib* (the Pure), and *Al-Barr* (the Source of every good). Contemplating these names nourishes the believer's awareness of cleanliness in both its inner and outer aspects. The strongest practical instrument of inner cleansing is repentance; the [dua archive](https://getvaaz.com/en/dua) holds repentance and istighfar supplications which, combined with the dhikr in the [daily dhikr guide](https://getvaaz.com/en/blog/daily-dhikr-guide), build a daily discipline of purification. For the inner cleansing of repentance, see [Sermon on Tawbah](https://getvaaz.com/en/blog/sermon-on-tawbah); for the inner sincerity that keeps the heart polished, see [Sermon on Ikhlas](https://getvaaz.com/en/blog/sermon-on-ikhlas). Cleanliness is like a two-winged bird that extends from the body into the heart; the believer flies with both wings together. May Allah make us among those who repent and those who purify themselves, those who earn the promise of Al-Baqarah 2:222. *Amin.* ## References 1. The Noble Qur'an, Surah Al-Alaq 96:1-5. 2.
