It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that whenever the Messenger of Allah (peace and blessings be upon him) obtained spoils of war, he (peace and blessings be upon him) would order Sayyiduna Bilal (may Allah be pleased with him), and he would make an announcement among the people. The people would bring their spoils, and he (peace and blessings be upon him) would take out a fifth (khums) from it and distribute the rest. (Once) after this announcement, a man came with a halter made of hair and said: O Messenger of Allah, this is (from) what we obtained of the spoils (which I have now brought). He (peace and blessings be upon him) asked: "Did you hear Bilal's announcement made three times?" He said: Yes. He (peace and blessings be upon him) said: "Then what prevented you from bringing it?" He offered some excuse, so he (peace and blessings be upon him) said: "Now you yourself will bring it on the Day of Resurrection; I will never accept it from you now." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
