4. Ali ibn Ibrahim has narrated from his father from ibn Mahbub from ‘Abd Allah ibn Sinan who has said the following: “This is concerning my question before abu ‘Abd Allah , about the case of a man who gave his sheep to a man for maintenance in exchange for Ghee and a certain amount of dirham for every sheep every month. He (the Imam) said, ‘It is not unlawful in exchange for dirham, however, for ghee, I do not like unless they give milk.’”
