Musannaf Ibn Abi Shaybah 22305 — A man who lends a loan to another

Ibn Harmalah (may Allah have mercy on him) said: I sold a she-camel on the condition that I would receive dirhams in exchange on the day of the harvest. When the time for delivery came, they paid me in wheat, barley and sult (hull-less barley), so I asked Sa'id bin al-Musayyib (may Allah have mercy on him). He said: This is not proper; do not take anything other than dirhams.
