The morsel a person eats nourishes more than the body — it nourishes their supplication, their worship, and their Hereafter. Islam does not disdain the pursuit of sustenance; on the contrary, it counts earning a livelihood through lawful means as the path of the prophets. Yet it also places the question of whether that income is lawful or unlawful at the very centre of life. This sermon examines the Quranic foundation of lawful earnings, the harm unlawful income does to worship, the measure for avoiding doubtful gains, and the balance between work and reliance on Allah.
Why Do Lawful Earnings Matter So Much?
In Islamic thought the concept of kasb covers every kind of earning and acquisition in a person's religious, moral, and economic life. As the Turkish Religious Foundation's Encyclopaedia of Islam (TDV) notes in its entry on kasb, working and securing one's livelihood through lawful means is behaviour the religion actively encourages; even the ordering of the day for earning and the night for rest is read as part of this design.
Lawful earning is not merely an economic matter. The source of the food a person eats directly shapes the servant's relationship with Allah, because a body fed on the unlawful (haram) loses the blessing of worship and supplication. This is precisely why scholars have regarded securing one's basic needs through lawful means as a responsibility rising to the level of an obligation.
The Quran on Lawful and Wholesome Sustenance
Allah invites humankind to benefit from the bounties of the earth, but sets one boundary: what is lawful and good. In Surah al-Baqarah, all of humanity is addressed:
— Surah al-Baqarah, 168O mankind, eat of what is lawful and good on the earth, and do not follow the footsteps of Satan; indeed, he is a clear enemy to you.
The warning that follows reminds us that the unlawful is often adorned and enticing: Satan urges a person only towards "evil and immorality, and towards saying about Allah what you do not know" (al-Baqarah, 169). As the Diyanet commentary explains, "lawful" (halal) here means what is religiously permitted with no prohibition attached, while "good" (tayyib) describes what balanced, virtuous, sound-natured people find agreeable — pure and beneficial. The point is not only that a thing is physically clean, but that the manner in which it was earned is legitimate.
The address to the believers is even more specific:
— Surah al-Baqarah, 172O you who believe, eat from the good things We have provided for you, and give thanks to Allah, if it is Him you worship.
Notice that eating from the good of one's provision is mentioned together with gratitude and worship. The lawful morsel is the ground that makes gratitude possible; the unlawful morsel quietly corrodes both gratitude and servitude.
Eating from the Work of One's Own Hands
The Prophet Muhammad (peace be upon him) described the sustenance a person earns by their own labour as the most excellent of earnings:
— Sahih al-Bukhari, Sales 15, no. 2072Nobody has ever eaten a better meal than that which one has earned by working with one's own hands. The Prophet of Allah, David, used to eat from the earnings of his manual labour.
This hadith sums up the value the religion places on work and on earning by the sweat of one's brow. David (Dawud), though a prophet and a king, supported himself by making armour. Earning through effort does not diminish a person; rather, it makes them a partner on the road of the prophets. Islam does not look kindly on begging or living off others, nor does it accept dressing up idleness as reliance on Allah. Our companion piece, the sermon on commerce, extends this theme to the etiquette and limits of seeking sustenance through lawful trade.
How Unlawful Income Harms Supplication and Worship
The most striking warning about lawful earnings is the hadith describing how the unlawful morsel veils a person's supplication:
— Sahih Muslim, Zakat 19, no. 1015O people, Allah is Good (Tayyib) and accepts only that which is good. And Allah commanded the believers as He commanded the messengers, saying: "O messengers, eat of the good things and do righteous deeds"; and He said: "O you who believe, eat of the good things We have provided you." Then he mentioned a man who travels widely, dishevelled and covered in dust, who stretches his hands towards the sky, "O Lord, O Lord," while his food is unlawful, his drink is unlawful, his clothing is unlawful, and he is nourished by the unlawful — so how can his supplication be answered?
This hadith shows how every apparent condition for an answered du'a — the nearness of a long journey, hands raised open, insistent calling upon the Lord — can be undone by the unlawful morsel. Even when a person performs the outward form of worship faultlessly, a veil is drawn before their supplication if their income is stained with the unlawful. For this reason the pious of old said: if you seek an answer to your prayer, first make your morsel lawful.
Riba (interest), the rights owed to others, deception, bribery, and unjust gain do not stain only that money; they reach into the food bought with it, the rent paid from it, and the family fed by it. We examined why riba is counted among the gravest financial sins in our article, what is riba in Islam.
Guarding Against Doubtful Earnings
Like every area of life, earning is not always divided by a sharp line between the plainly lawful and the plainly unlawful; between them lies a doubtful zone. The Prophet defined the stance to take there:
— Sahih al-Bukhari, Faith 39, no. 52The lawful is clear and the unlawful is clear, and between the two are doubtful matters that many people do not know. Whoever guards against the doubtful preserves his religion and his honour, and whoever falls into the doubtful falls into the unlawful... Truly, in the body there is a morsel of flesh: if it is sound, the whole body is sound, and if it is corrupt, the whole body is corrupt. Truly, it is the heart.
This hadith turns lawful earning into a matter of the heart. If a person is unsure of the source of an income, they should not cast caution aside and march upon the doubtful reasoning that "it is not definitely unlawful anyway." Avoiding the doubtful is a protective boundary drawn around one's religion and one's honour. This sensitivity forms one whole together with other moral measures concerning wealth, such as those in our sermon on wastefulness and miserliness.
The Balance Between Work and Reliance on Allah
Some have fallen into the error of imagining that working contradicts reliance upon Allah (Tawakkul). Yet Islamic scholars have seen these two concepts not as opposites but as complements. As the TDV Encyclopaedia of Islam relates, Imam Muhammad ibn al-Hasan al-Shaybani, in his work Kitab al-Kasb, refuted with both rational and transmitted evidence the claim of certain ascetics that "work contradicts Tawakkul," stressing that lawful earning is the way of the prophets and that the ordering of the world depends upon acquisition.
True reliance on Allah is not the abandonment of means, but entrusting the outcome to Allah after taking hold of the means. The working hand is the most natural partner of the supplicating tongue. A person both tills their field and prays, "My Lord, grant blessing." Among the principles of lawful earning in al-Ghazali's Ihya 'Ulum al-Din are avoiding deception, performing one's work with competence, keeping away from illegitimate paths such as riba and hoarding, and honouring the rights of both worker and employer.
Practical Measures for Lawful Earning
- Question the source. If you doubt whether a means of earning is lawful, do not press on without asking someone qualified; leave the doubtful.
- Rely on effort and honesty. A little wealth earned by the sweat of the brow, without deceit, is better than much wealth earned unlawfully — because it carries blessing.
- Fear the rights of others. Pay the worker's wage on time, give full measure in trade, and do not delay a debt. A right owed to another is not closed by repentance alone, but only by seeking mutual forgiveness.
- Feed your worship with your earnings. The lawful morsel gives wings to your supplication and prayer; the unlawful weighs down even the most sincere act of worship.
- Hold on to contentment. Being content with the lawful of one's provision is the strongest shield against chasing after the unlawful.
Conclusion
Lawful earning is not merely a matter of the wallet; it is a matter of faith and character. As long as the morsel a person eats is pure, their supplication rises to the heavens, their worship is blessed, and peace enters their home. As soon as the unlawful is mixed in, even the most impressive fortune loses its blessing. We ask our Lord to provide for us from what is lawful, to protect us from the unlawful and the doubtful, and to grant us contentment with and gratitude for a lawful livelihood, however modest.
