Chapter: As-Salam for a fixed specified period

The Prophet (ﷺ) came to Medina and the people used to pay in advance the prices of fruits to be delivered within two to three years. The Prophet (ﷺ) said (to them), "Buy fruits by paying their prices in advance on condition that the fruits are to be delivered to you according to a fixed specified measure within a fixed specified period." Ibn Najih said, "... by specified measure and specified weight."

Abu Burda and `Abdullah bin Shaddad sent me to `Abdur Rahman bin Abza and `Abdullah bin Abi `Aufa to ask them about the Salaf (Salam). They said, "We used to get war booty while we were with Allah's Messenger (ﷺ) and when the peasants of Sham came to us we used to pay them in advance for wheat, barley, and oil to be delivered within a fixed period." I asked them, "Did the peasants own standing crops or not?" They replied, "We never asked them about it."
