Those who disliked consuming the profit of what one has not taken liability for

Mujahid (may Allah have mercy on him) said: I said to Abd al-Rahman bin Abi Layla: "Narrate to me the hadith in which you have gathered for me the kinds of usury (riba)." He said: "Never consume the profit of anything for whose loss you do not bear liability."

It is narrated from Amr bin Shu'ayb that the Prophet (peace and blessings be upon him) sent Sayyiduna Attab bin Asid (may Allah be pleased with him) to the people of Makkah and said: "Do you know where I have sent you? I have sent you to the people of Allah." Then he said: "Forbid them four things: a sale combined with a loan; two conditions in one sale; using the profit of a thing for whose loss one does not bear liability (that is, unless one shares in both the profit and the loss, one may not use the profit); and selling what one does not have."

It is narrated from Amr bin Shu'ayb that whenever his grandfather sent out goods for trade, he would forbid them from a sale combined with a loan, from two conditions in one sale, and from using the profit of a thing for whose loss they did not bear liability (that is, unless one shares in both the profit and the loss, one may not use the profit).
