The Qur'an opens its longest surah on practical law with this very command: *O you who believe, fulfil your contracts* (Al-Ma'idah 5:1). It elsewhere says, *Fulfil the covenant, for the covenant will be questioned* (Al-Isra 17:34). A promise to Allah is heavier still; breaking one's word is listed by the Prophet as one of the three marks of a hypocrite. A believer does not promise what they cannot keep, and does not abandon what they have promised except by genuine necessity. A promise is not a sentence. It is the holder's honour, integrity, and moral existence put on the line in a single word. To break a promise injures the listener — and reduces the speaker. This sermon explores the path Allah has opened in the Qur'an on the keeping of covenants, the concrete examples from the life of the Prophet Muhammad (peace be upon him), and the believer's living principle: *a Muslim keeps their word.* ## Fulfil Your Contracts Surah Al-Ma'idah opens with a command to the believers. The first directive is not an act of worship nor a prohibition; it is fidelity to covenants: > يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ أَوۡفُواْ بِٱلۡعُقُودِ > O you who believe, fulfil your contracts. Surah Al-Ma'idah 5:1 That the longest surah of legal content in the Qur'an begins not with worship or prohibition but with *"fulfil your contracts"* is deliberate. A believer lives inside a network of covenants — beginning with the covenant given to Allah and extending out to every promise made to people. The mother's word to her child, the employer's promise to her staff, the seller's commitment to her customer, the citizen's pledge to his country — every one is a reflection of the same morality. Surah Al-Isra adds that a covenant is a thing that *will be asked about:* > وَأَوۡفُواْ بِٱلۡعَهۡدِۖ إِنَّ ٱلۡعَهۡدَ كَانَ مَسۡـُٔولࣰ ا > And fulfil the covenant. Indeed, the covenant will be questioned. Surah Al-Isra 17:34 A believer is one who knows the weight of giving a word. For this reason they do not give it cheaply; once given, they do not forget that the day will come when it is asked back. ## A Promise to Allah Weighs Heavier Still If betrayal of a human promise is severe, the betrayal of a promise made to Allah is many times heavier: > وَأَوۡفُواْ بِعَهۡدِ ٱللَّهِ إِذَا عَٰهَدتُّمۡ وَلَا تَنقُضُواْ ٱلۡأَيۡمَٰنَ بَعۡدَ تَوۡكِيدِهَا وَقَدۡ جَعَلۡتُمُ ٱللَّهَ عَلَيۡكُمۡ كَفِيلًاۚ إِنَّ ٱللَّهَ يَعۡلَمُ مَا تَفۡعَلُونَ > Fulfil the covenant of Allah when you have entered into it. And do not break oaths after they have been confirmed, while you have made Allah a witness over you. Indeed, Allah knows what you do. Surah An-Nahl 16:91 The moment Allah's name is invoked in an oath, the promise rises to the level of an act of worship. To break it is treachery against Allah Himself. The Qur'an describes this betrayal in three powerful verses revealed about the story of Tha'labah ibn Hatib: > ۞وَمِنۡهُم مَّنۡ عَٰهَدَ ٱللَّهَ لَئِنۡ ءَاتَىٰنَا مِن فَضۡلِهِۦ لَنَصَّدَّقَنَّ وَلَنَكُونَنَّ مِنَ ٱلصَّٰلِحِينَ. فَلَمَّآ ءَاتَىٰهُم مِّن فَضۡلِهِۦ بَخِلُواْ بِهِۦ وَتَوَلَّواْ وَّهُم مُّعۡرِضُونَ. فَأَعۡقَبَهُمۡ نِفَاقࣰ ا فِي قُلُوبِهِمۡ إِلَىٰ يَوۡمِ يَلۡقَوۡنَهُۥ بِمَآ أَخۡلَفُواْ ٱللَّهَ مَا وَعَدُوهُ وَبِمَا كَانُواْ يَكۡذِبُونَ > Among them are those who promised Allah, "If He gives us of His bounty, we will surely give charity and we will surely be among the righteous." But when He gave them of His bounty, they hoarded it and turned away in aversion. So He produced in their hearts hypocrisy until the Day they will meet Him — because they broke what they had promised to Allah, and because they used to lie. Surah At-Tawbah 9:75-77 The one who breaks his promise does not merely fail outwardly; something also falls inside. *"He produced in their hearts hypocrisy"* is precisely the inner collapse. So long as a person keeps breaking their word, the believer in them drifts further from sincerity. ## Do Not Say What You Will Not Do — The Warning of Surah As-Saff The most basic rule about giving a promise appears in Surah As-Saff: > يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لِمَ تَقُولُونَ مَا لَا تَفۡعَلُونَ > O you who believe, why do you say what you do not do? Surah As-Saff 61:2 It is reported that this verse was revealed after some of the Companions said, *"If we knew which deed is most beloved to Allah, we would give our wealth and our lives for it,"* and then some of those same people turned back at the Battle of Uhud. The bigger the promise, the heavier the duty to keep it; the believer therefore does not say what they cannot do, and does not promise what they cannot fulfil. To make a promise is to assume a responsibility. Too heavy to be made lightly; too noble to be refused. Allah's warning here reminds us that even careless promises will be brought before Him. ## The Believer's Portrait — Al-Baqarah 177 One of the most comprehensive verses of Surah Al-Baqarah lists keeping promises among the defining features of the truly righteous: > وَٱلۡمُوفُونَ بِعَهۡدِهِمۡ إِذَا عَٰهَدُواْ > ...and those who fulfil their promise when they make a promise. Surah Al-Baqarah 2:177 After listing the six articles of faith, feeding the orphan and the wayfarer, prayer, zakat, and patience, the verse caps the chain with *"those who fulfil their promise."* This is the Qur'anic portrait of the believer; fidelity to one's word is one of its main lines. ## The Believer's Portrait — Al-Ahzab 23 and Anas ibn an-Nadr Those who keep their promise hold a special station with Allah. Surah Al-Ahzab describes them: > مِّنَ ٱلۡمُؤۡمِنِينَ رِجَالࣱ صَدَقُواْ مَا عَٰهَدُواْ ٱللَّهَ عَلَيۡهِۖ فَمِنۡهُم مَّن قَضَىٰ نَحۡبَهُۥ وَمِنۡهُم مَّن يَنتَظِرُۖ وَمَا بَدَّلُواْ تَبۡدِيلࣰ ا > Among the believers are men who have been true to what they promised Allah. Among them is he who has fulfilled his vow [by death], and among them is he who awaits — and they have not changed in the least. Surah Al-Ahzab 33:23 Anas ibn Malik (may Allah be pleased with him) says this verse was revealed regarding his uncle Anas ibn an-Nadr. ### The Vow of Anas ibn an-Nadr Anas ibn an-Nadr had been absent from the Battle of Badr. He came to the Prophet and said, *"O Messenger of Allah, I was not present at the first battle you fought against the polytheists. If Allah ever brings me to face them in battle, Allah will surely see what I do."* The day of Uhud came. As the Muslims faltered, Anas ibn an-Nadr advanced. *"O Allah,"* he said, *"I disassociate myself from what these (the retreating Muslims) have done, and I disavow what the polytheists have done."* He met Sa'd ibn Mu'adh and said: *"O Sa'd, I want Paradise. By the Lord of an-Nadr, I find its fragrance from Uhud."* He charged into the enemy. When he was martyred his body was counted with more than eighty wounds from swords, spears, and arrows. The polytheists had so mutilated him that his sister could only identify him by the tip of his fingers. > Anas ibn an-Nadr had promised Allah that he would fight unflinchingly the next time he met the enemy. He paid that promise not with his tongue but with his blood. Allah Himself made his fidelity eternal in Al-Ahzab 23 — a single verse that fixes the meaning of a kept word. ## Stories — The Collapse of a Broken Promise ### Tha'labah ibn Hatib and the Zakat Collectors Tha'labah ibn Hatib was a poor man. One day he came to the Prophet and said, *"O Messenger of Allah, pray that Allah grants me wealth."* The Prophet's reply was a warning: — *"Tha'labah, a little wealth from which you discharge its rights is better than much wealth you cannot bear."* Tha'labah insisted: *"I swear by the One who sent you with the truth, if Allah grants me wealth, I will give every entitled person their due."* The Prophet prayed for him. Tha'labah grew very wealthy. First he attended the mosque less often. When his herds outgrew Medina, he withdrew to a remote valley; soon he stopped coming even to the Friday prayer. The Prophet sent two zakat collectors. Tha'labah turned them away, saying, *"This zakat is no different from tribute."* The Prophet said twice, *"Woe to Tha'labah!"* Surah At-Tawbah 75-77 was revealed about this very incident. It is narrated that Tha'labah later sought to bring his zakat himself, but the Prophet refused to accept it; the moment he broke his word, the matter had passed from his hands. ### The Vow (Nadhr): A Promise to Allah Raised to the Level of Worship A *nadhr* is a vow in which a person commits to an act of worship they were not otherwise required to perform — *"If my matter is settled, I will fast so many days"; "If I am cured of this illness, I will sacrifice an animal."* Allah commands in Surah Al-Hajj, *"...and let them fulfil their vows"* (Al-Hajj 22:29). The Prophet (peace be upon him) said: > Whoever vows to obey Allah, let him obey (carry out his vow). And whoever vows to disobey Allah, let him not disobey Him (his vow is not to be fulfilled). Ibn Abbas (may Allah be pleased with him) reports: *"While the Prophet was delivering the Friday sermon, he saw a man standing. He asked who it was. They said, 'It is Abu Israil, who has vowed to fast, to stand, to remain in the sun, not to sit, and not to speak.' The Prophet said: 'Tell him to sit, take shade, speak — but to fulfil his fast.'"* In other words, the portion of a vow that is genuine worship must be fulfilled; the part that is self-inflicted hardship is not binding. The detailed rulings on vows form a full chapter of Islamic jurisprudence; for the purposes of this sermon, the central point is that a believer does not turn back on a word given to Allah. Once Allah's name is invoked, what was a sentence becomes a debt. ## The Hadith About Whom Allah Will Be the Plaintiff Against Breaking a promise is a sin so grave that the Prophet narrates a divine saying about three people against whom Allah Himself will be the plaintiff: > Allah, Exalted is He, said: I will be the plaintiff against three on the Day of Resurrection: a man who swore by My name and then broke his oath; a man who sold a free person as a slave and consumed the price; and a man who hired a worker, took the full work from him, and did not pay his wage. The first of the three is the one who broke his oath. That he is mentioned in the same breath as the employer who cheats his worker is significant: fidelity to one's word and everyday justice are wrapped together. ## One of the Three Marks of Hypocrisy The Prophet makes plain that breaking one's word is one of the four behaviours that strip the believer of trustworthiness: > Four things — whoever has them is a pure hypocrite, and whoever has any of them carries a trait of hypocrisy until he leaves it: when he speaks he lies, when he promises he breaks his promise, when he is entrusted he betrays the trust, and when he disputes he turns to falsehood. Sahih Muslim adds: *"Even if he fasts, prays, and considers himself a Muslim."* This last clause is the warning that no outward shine compensates for the inner fracture that comes from breaking one's word. ## A Practical Guide — Before You Promise, and After You Have Kept There are concrete points in a believer's daily life where the question of covenant must be paused over: - **Learn the real meaning of *insha'Allah.*** *Insha'Allah* means *if Allah wills.* But to say *"I will be there at 3, insha'Allah"* and then to skip out by saying *"but I said insha'Allah"* is contrary to its spirit. *Insha'Allah* is not an escape clause; it is a reverence clause. - **Measure before you promise.** *"I will do it for you"* must be weighed before it is spoken. This is the direct command of As-Saff 61:2. - **When you promise, write.** Memory is fallible; writing is the believer's extension of memory. The Qur'anic command in Al-Baqarah 282 to write down debts is also a practical measure for preserving covenants. - **When you realise you cannot fulfil a promise, communicate early.** The way to ease the pain of a broken promise is not to spring it on the listener at the last moment; it is to communicate as early as possible. - **Do not separate promises to Allah from promises to people.** They are links of the same chain. Slipping on one drags you toward slipping on the other. ## Putting Fidelity 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-Wahhab* (the Bestower), *Al-Haqq* (the True), and *Al-Mu'min* (the Bestower of Security) — the contemplation of these names is a steady source for one's own fidelity. For the repair of broken vows in the past, the [dua archive](https://getvaaz.com/en/dua) provides repentance and istighfar supplications; combined with the dhikr in the [daily dhikr guide](https://getvaaz.com/en/blog/daily-dhikr-guide), they build a daily discipline of honour. For the close relationship between word and covenant, see [Sermon on Honesty](https://getvaaz.com/en/blog/sermon-on-honesty); for the inner sincerity that makes covenants possible at all, see [Sermon on Ikhlas](https://getvaaz.com/en/blog/sermon-on-ikhlas). A word is not just a sentence; it is the network of covenants the believer holds with Allah, with their own self, and with people. Fidelity to one's word is the crown of the believer's moral summit. May Allah make us among His servants who are true to the covenant they made with Him and to every word they give to His creation. *Amin.* ## References 1. The Noble Qur'an, Surah Al-Ma'idah 5:1. 2.
