Musannaf Ibn Abi Shaybah 23870 — A man who hands over sheep and goats

Umayr said: We used to give the owners of sheep and goats something on condition that they would give us so much cheese, so much ghee and so much of the yellowish liquid (whey). Then I asked Alqamah, Masruq and Abd al-Rahman bin Abi Layla about it, and all of them forbade me from it.
