إِن تَجْتَنِبُوا۟ كَبَآئِرَ مَا تُنْهَوْنَ عَنْهُ نُكَفِّرْ عَنكُمْ سَيِّـَٔاتِكُمْ وَنُدْخِلْكُم مُّدْخَلًۭا كَرِيمًۭا
If you avoid the major sins which you are forbidden, We will remove from you your lesser sins and admit you to a noble entrance [into Paradise].
O you who believe! Eat not up your property among yourselves unjustly except it be a trade amongst you, by mutual consent. And do not kill yourselves (nor kill one another). Surely, Allah is Most Merciful to you (29)And whoever commits that through aggression and injustice, We shall cast him into the Fire, and that is easy for Allah (30)If you avoid the great sins which you are forbidden to do, We shall remit from you your (small) sins, and admit you to a Noble Entrance (i.e. Paradise)(31)
Prohibiting Unlawfully Earned Money
Allah, the Exalted and Most Honored, prohibits His believing servants from illegally acquiring each other's property using various dishonest methods such as Riba, gambling and other wicked methods that appear to be legal, but Allah knows that, in reality, those involved seek to deal in interest.
Ibn Jarir recorded that Ibn 'Abbas commented on a man who buys a garment, saying that if he likes it he will keep it, or he will return it along with an extra Dirham, "This is what Allah meant, when He said,
وَلَا تَأْكُلُوا أَمْوَالَكُم بَيْنَكُم بِالْبَاطِلِ
(Eat not up your property among yourselves unjustly.")[2:188] 'Ali bin Abi Talhah reported that Ibn 'Abbas said, "When Allah sent down,
يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَأْكُلُوا أَمْوَالَكُم بَيْنَكُم بِالْبَاطِلِ
(O you who believe! Eat not up your property among yourselves unjustly) some Muslims said, 'Allah has forbidden us from eating up each other's property unjustly, and food is our best property. Therefore, none among us is allowed to eat from anyone else's food.' After that Allah sent down,
لَّيْسَ عَلَى الْأَعْمَىٰ حَرَجٌ
(There is no restriction on the blind)(until the end of the Ayah). [24:61].'" Qatadah said similarly. Allah's statement,
إِلَّا أَن تَكُونَ تِجَارَةً عَن تَرَاضٍ مِّنكُمْ
(except it be a trade amongst you, by mutual consent.) means, do not revert to illegal ways and means to acquire money. However, there is no harm in commercial transactions that transpire between the buyer and the seller with mutual consent, so that money is legally earned from these transactions. Mujahid said that,
إِلَّا أَن تَكُونَ تِجَارَةً عَن تَرَاضٍ مِّنكُمْ
(except it be a trade amongst you, by mutual consent.) means, "By selling and buying, or giving someone a gift." Ibn Jarir recorded this statement.
The Option to Buy or Sell Before Parting, is Part of 'Mutual Consent' in Trading
Mutual agreement in various transactions is attained when both parties have the right to uphold or dissolve the agreement before they part. In the Two Sahihs, it is recorded that the Messenger of Allah ﷺ said,
الْبَيِّعَانِ بِالْخِيَارِ مَالَمْ يَتَفَرَّقَا
(The seller and the buyer retain the (right to change their mind) as long as they have not parted.) Al-Bukhari's wording for this Hadith reads,
إِذَا تَبَايَعَ الرَّجُلانِ فَكُلُّ وَاحِدٍ مِنْهُمَا بِالْخِيَارِ، مَالَمْ يَتَفَرَّقَا
(When two men conduct a transaction, they retain their (right to change their mind) as long as they have not parted.)
Forbidding Murder and Suicide
Allah said,
وَلَا تَقْتُلُوا أَنفُسَكُمْ
(And do not kill yourselves.) by committing Allah's prohibitions, falling into sin and eating up …
