Yahya related to me from Malik that Muhammad ibn Abdullah ibn Abi
Maryam asked Said ibn al-Musayyab's advice. "I am a man who buys food
with receipts from al-Jar. Perhaps I will buy something for a dinar
and half a dirham, and will be given food for a half." Said said, "No.
You give a dirham, and take the rest in food." (A half dirham did not
exist as a coin.)
