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, o

﴿وَلاَ تَأْكُلُواْ أَمْوَلَكُمْ بَيْنَكُم بِالْبَاطِلِ﴾

(Eat not up your property among yourselves unjustly.'') `Ali bin Abi Talhah reported that Ibn `Abbas said, "When Allah sent down,

﴿يَـأَيُّهَا الَّذِينَ ءَامَنُواْ لاَ تَأْكُلُواْ أَمْوَلَكُمْ بَيْنَكُمْ بِالْبَـطِلِ﴾

(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 الاٌّعْمَى حَرَجٌ﴾

(There is no restriction on the blind) (until the end of the Ayah). ﴿24:61﴾.''' Qatadah said similarly. Allah's statement,

﴿إِلاَّ أَن تَكُونَ تِجَـرَةً عَن تَرَاضٍ مِّنْكُمْ﴾

(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,

﴿إِلاَّ أَن تَكُونَ تِجَـرَةً عَن تَرَاضٍ مِّنْكُمْ﴾

(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.
