Sahih Bukhari Volume 8, Book 73, Hadith Number 179.

Narated By Um Hani : (The daughter of Abu Talib) I visited Allah’s Apostle in the year of the Conquest of Mecca and found him taking a bath, and his daughter, Fatima was screening him. When I greeted him, he said, “Who is it?” I replied, “I am Um Hani, the daughter of Abu Talib.” He said, “Welcome, O Um Hani ! ” When the Prophet had finished his bath, he stood up and offered eight Rakat of prayer while he was wrapped in a single garment. When he had finished his prayer, I said, “O Allah’s Apostle! My maternal brother assumes (or claims) that he will murder some man whom I have given shelter, i.e., so-and-so bin Hubaira.” Allah’s Apostle said, “O Um Hani! We shelter him whom you have sheltered.” Um Hani added, “That happened in the forenoon.”
