Hadith 607:1
Musa ibn Dawud narrated to us, Layth ibn Sa'd narrated to us, from Sahl ibn Mu'adh, from his father, who said: The Messenger of Allah, peace and blessings of Allah be upon him, said: "Ride these animals while they are healthy, and leave them while they are healthy, and do not take them as chairs."
حدثنا موسى بن داود، حدثنا ليث بن سعد، عن سهل بن معاذ، عن أبيه، قال: قال رسول الله صلى الله عليه وسلم: " اركبوا هذه الدواب سالمة، وايتدعوها سالمة، ولا تتخذوها كراسي "
