Zuhayr bin Harb زهير بن حرب بن شداد أبو خثيمة · Wages (Kitab Al-Ijarah)

The Messenger of Allah (ﷺ) forbade a townsman to sell for a man from the desert. I asked: What do you mean by the selling of a townsman for a man from the desert ? He replied: He should not be a broker for him.

Hakim asked (the Prophet): Messenger of Allah, a man comes to me and wants me to sell him something which is not in my possession. Should I buy it for him from the market? He replied: Do not sell what you do not possess.

The Prophet (ﷺ) as saying: The milk of milch camels may be drunk for payment when in pledge, and the animal may be ridden for payment when it is pledge; payment being made by the one who rides and the one who drinks. Abu Dawud said: In our opinion this is correct.
