Sayyiduna Qurrah bin Da'mus (may Allah be pleased with him) said: I came to Madinah, and the Prophet (peace and blessings be upon him) was seated, and the Companions (may Allah be pleased with them) were around him (peace and blessings be upon him). I wanted to come close and sit near him (peace and blessings be upon him), but I could not get close. Then I said: O Messenger of Allah! Seek forgiveness for your Numayri servant. He (peace and blessings be upon him) said: "Ghafara Allahu laka" (May Allah forgive you). He said: The Messenger of Allah (peace and blessings be upon him) sent al-Dahhak (may Allah be pleased with him) as a collector, and he brought back a large camel. The Prophet (peace and blessings be upon him) said to him: "You went to Hilal bin Amir, Numayr bin Amir and Amir bin Rabi' and took the finest of their wealth." He said: O Messenger of Allah (peace and blessings be upon him)! I heard you (peace and blessings be upon him) mentioning a military expedition, so I wanted to bring a camel that you (peace and blessings be upon him) could ride, and your Companions (may Allah be pleased with them) too. He (peace and blessings be upon him) said: "By Allah! What you left behind was dearer to me than what you have brought. Go and return it, and collect the zakah from their ordinary wealth."
