Sayyidah Umm Hani (may Allah be pleased with her) said: When it was the day of the Conquest of Makkah, the Messenger of Allah (peace and blessings be upon him) called for water, and Umm Hani, Umm Sulaym and the mother of Anas bin Malik (may Allah be pleased with them) put up a screen with a sheet. Then he (peace and blessings be upon him) entered the house of Umm Hani and prayed four rak'ahs of Duha (the forenoon prayer).
