Sahih al-Bukhari 2873

It is related that Abu Murra, the mawla of Umm Hani' bint Abi Talib, heard Umm Hani' bint Abi Talib say, "I went to the Messenger of Allah, may Allah bless him and grant him peace, in the year of the Conquest of Makka and found him doing ghusl, while his daughter Fatima was screening him. I greeted him and he said, 'Who is this?' I said, 'It is Umm Hani' bint Abi Talib.' He said, 'Welcome, Umm Hani'.' When he finished his ghusl, he stood up and prayed eight rak'ats wrapped in a single cloth. When he finished, I said, 'Messenger of Allah, my brother claims that he is going to kill a man to whom I have given sanctuary. It is so-and-so, the son of Hubayra.' The Prophet, may Allah bless him and grant him peace, said, 'We give sanctuary to the one to whom you have given sanctuary, Umm Hani'.'" Umm Hani' said that that happened in the morning. X: The dhimma and sanctuary of the Muslims is the same, and it is effected by the lowest of them
