Hadith.3777 - It is narrated from Abd Al-Samad ibn Bashir, from Abu Abdillah : Muhammad ibn Al-Qasim Al-Hannat asked him, "May Allah (swt) keep you well. I sell food to a man on credit, and when I go to collect payment, the price of the food has changed, and he says, 'I do not have dirhams.' What should I do?" Imam said: "Take from him at the price of the day." Muhammad asked: "I understand, may Allah (swt) keep you well, but what if it is the same food he purchased from me?" Imam said: "Do not take it from him until he sells it and gives you the payment." Muhammad said: "May Allah (swt) humble me! He initially gave me a concession, but when I questioned further, he imposed a stricter rule upon me."
