Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said that the Messenger of Allah (peace and blessings be upon him) said to Attab bin Asid (may Allah be pleased with him): "I am sending you to the people of Allah and the people of Makkah. Forbid them from selling a thing before they take possession of it, or from profiting from something for whose loss they have not accepted responsibility, and (forbid them) concerning a loan and a sale, two conditions in one sale, and a sale and a loan."
Yahya bin Salih al-Ayli alone narrated it, and it is munkar (denounced) with this chain.
