Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Amr bin Shu’aib that when the Messenger of Allah (peace and blessings be upon him) returned from Hunain after Ta’if, he said: “Collect (even) the needle and thread, because betrayal in spoils of war is (a cause for) Hell, and for the betrayer there will be disgrace and shame on the Day of Resurrection.” Then the Prophet (peace and blessings be upon him) took hold of a hair from a camel and said, “There is not even this much for me from your wealth except the fifth (khums), and even the fifth (in the end) is returned to you.”
