[Machine] The Messenger of Allah ﷺ said: "It is not permissible to engage in a transaction without a clear price, nor is it permissible to make conditions in a transaction, and there is no profit in a transaction unless it is guaranteed. And do not sell what you do not possess." And Ismail ibn 'Ulayah narrated from Ayyub, who said: "Amr ibn Shu'ayb narrated to me, who said: "My father narrated to me, until Abdullah ibn Amr mentioned it." Abu Ali al-Rudhbary informed us that Muhammad ibn Bakr informed him, narrating from Abu Dawud, who narrated from Zuhayr ibn Harb, who narrated from Ismail, and he mentioned it.
