Haritha bin Mudarrib says: I performed Hajj in the company of Sayyiduna Umar bin Khattab (may Allah be pleased with him). The noble people of Syria came and said: O Commander of the Faithful! We have become owners of slaves and animals, and we wish that you collect zakat from us on these properties so that our wealth may be purified and this may be a means of purification for us. But he (may Allah be pleased with him) said: The two personalities before me (the Messenger of Allah, peace and blessings be upon him, and Sayyiduna Abu Bakr, may Allah be pleased with him) did not do this act, but you should wait so that I may consult with other Muslims about this matter.
