Musnad Ahmad 30:1776

'Abd al-Razzaq narrated to us, he said: Sufyan informed us, from Salamah ibn Kuhayl, from Abu Salamah, from Abu Hurayrah, who said: A Bedouin came demanding a camel from the Prophet, peace and blessings of Allah be upon him. The Prophet, peace and blessings of Allah be upon him, said: "Seek for him one of the same age as his camel." He said: So they sought one for him, but they found nothing except one older than the age of his camel. He said: So they gave him one older than his camel. The Bedouin said: "You have fulfilled [my right] to me, may Allah fulfill [your reward] for you." The Prophet, peace and blessings of Allah be upon him, said: "Indeed, the best of you is the best of you in repayment."
