Prayers (Salat)
Chapter: To offer As-Salat (the prayers) with a single garment wrapped round the body
Narrated Abu Murra:
(the freed slave of Um Hani) Um Hani, the daughter of Abi Talib said, "I went to Allah's Messenger (ﷺ) in the year of the conquest of Mecca and found him taking a bath and his daughter Fatima was screening him. I greeted him. He asked, 'Who is she?' I replied, 'I am Um Hani bint Abi Talib.' He said, 'Welcome! O Um Hani.' When he finished his bath he stood up and prayed eight rak`at while wearing a single garment wrapped round his body and when he finished I said, 'O Allah's Messenger (ﷺ) !

" Um Hani added, "And that was before noon (Duha).
