Musannaf Ibn Abi Shaybah 39735 — Reports on Taif

It is narrated from Amr bin Shu'ayb that when the Messenger of Allah (peace and blessings be upon him) returned from Hunayn after al-Ta'if, he (peace and blessings be upon him) said: "Hand in (even) the needle and thread, for embezzlement from the spoils is Hellfire, and for the one who embezzles it is disgrace and humiliation on the Day of Resurrection." Then he (peace and blessings be upon him) took hold of a hair of a camel and said: "Not even this is mine from this wealth of yours, except the fifth, and even the fifth (in the end) goes back to you."
