It was narrated from Harithah bin Mudarrib that he did Hajj with ‘Umar bin al Khattab (رضي الله عنه). The nobles of Syria came to him ['Umar) and said: O Ameer al-Mu'mineen, we have acquired slaves and mounts, so take charity from our wealth in order to purify us thereby, and it will be zakah for us. He said: This is something that the two who came before me did not do; I shall wait until I ask the Muslims.
