Protection the Holy Prophet (sa) at the Conquest of Mecca
Hazrat Umm Hani (ra) bint Abi Talib narrates:
“When the Holy Prophet (sa) stayed in the elevated part of Mecca, two of my in-laws from the Bani Makhzum tribe ran away and came to me.” Hazrat Umm Hani (ra) further states, “My brother, Ali [bin Abi Talib] came to me and said, ‘By God! I will kill them both.’” Hazrat Umm Hani (ra) states: “I shut them both inside the house. I then went to the Holy Prophet (sa) in the upper part of Mecca. I found that he was bathing at the time using a container which had remnants of dough inside. His daughter, Hazrat Fatimah (ra) was holding a cloth for a covering around him. After bathing, the Holy Prophet (sa) changed his clothes and then offered eight rak‘aat [units of prayer] of voluntary prayer at mid-morning. After this, he turned to me and said, ‘Welcome O Umm Hani! What brings you here?’”
She then informed him about the incident with the two men and what Hazrat Ali (ra) had said about killing them and also that she had hid them inside her house. The Holy Prophet (sa) stated, “We also give refuge to whoever you granted refuge and I assure the safety of those whom you granted protection” i.e. the Holy Prophet (sa) ordered Hazrat Ali (ra) not to kill them.
