Abdullah bin al-Harith bin Nawfal (may Allah be pleased with him) said that Sayyidah Umm Hani (may Allah be pleased with her) saw the Prophet (peace and blessings be upon him) offering eight rak'ahs of the Duha prayer. She did not see the Prophet (peace and blessings be upon him) offer (such) a prayer before it nor after it, and she saw him praying in a (garment) whose two ends were crossed over one another.
