Sales in which a Price is paid for Goods to be Delivered Later (As-Salam)

Bukhari :: Book 3 :: Volume 35 :: Hadith 454

Narrated Al-A'mash:

We argued at Ibrahim's dwelling place about mortgaging in Salam. He said, "Aisha said, 'The Prophet bought some foodstuff from a Jew on credit and the payment was to be made by a definite period, and he mortgaged his iron armor to him."
