Sayyidah Umm Hani (may Allah be pleased with her) relates: On the day of the Conquest of Makkah, the Messenger of Allah (peace and blessings be upon him) encamped on the high ground of Makkah, and I came to him (peace and blessings be upon him). Then Abu Dharr (may Allah be pleased with him) came with a large bowl of water; I could see that it had a trace of dough in it. Then Abu Dharr (may Allah be pleased with him) screened him (peace and blessings be upon him), and he (peace and blessings be upon him) took a bath. Then the Prophet (peace and blessings be upon him) screened Abu Dharr (may Allah be pleased with him), and he (Abu Dharr (may Allah be pleased with him)) took a bath. Then he prayed eight rak'ahs, and that was at the time of Duha (the forenoon).
