English translation
3502. It was narrated from Mālik bin Anas that it was conveyed to him that 'Amr bin Shu'aib narrated from his father, that his grandfather said: "The Messenger of Allāh ﷺ forbade non-refundable advances. Mālik said: "That means, as we think – and Allāh knows best – that a man buys a slave or rents an animal and says: 'I will give you a Dinar on the condition that if I give up the merchandise, or the rental, then what I give you is yours to keep.'" (Hasan)
