Abu Hurairah said :
The Prophet ﷺ sent Umar b. al-Khattab to collect sadaqa (All the people paid the zakat but ibn-jamil, Khalid b. al-walid and al-abbas refused. So the Messenger of Allahﷺ said : Ibn-jamil is not (so much) objecting, but he was poor and Allah enriched him. As for Khalid b. Walid, you are wronging him, for he has kept back his courts of mail and weapons to use them in Allah’s path. As for al-Abbas, the uncle of the Messenger of Allahﷺ, I shall be responsible for it and an equal amount along with it. Then he said did you not know(Umar) that a man’s paternal uncle is of the same stock as the father or his father?
