Hadith 2377
Sayyiduna Abu Las Khuzai (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) gave us some weak camels from the zakat camels for riding during Hajj. So we said, "O Messenger of Allah, in our opinion these camels are not fit for riding." The Prophet (peace and blessings be upon him) said: "There is a devil on the hump of every camel, so when you are about to mount, say 'Bismillah' as He has commanded you. Then make full use of them for your service. Indeed, it is Allah Almighty who grants you the ride (and makes these animals subservient to you)."
