Musannaf Ibn Abi Shayba 13:3333

Abu Bakr narrated to us, he said: Abd al-A’la narrated to us, from Ma’mar, from al-Zuhri, he said: I asked him about a man who rents a thing, then rents it out for more than what he rented it for. He saw no harm in it. Then I asked him about it later, and he disliked it.
