Who said it and what is the occasion: “We have granted safety to the one you granted safety, O Umm Hani”?

Question:
This questioner, Muhammad, says: I ask you, Honorable Shaykh, about two phrases I read in one of the books. One phrase is: “We have granted safety to the one you granted safety, O Umm Hani.” What is the story behind that? May you be rewarded.

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, Lord of the worlds, and may Allah send prayers and peace upon our Prophet Muhammad. Umm Hani is the daughter of Abu Talib and the sister of 'Ali ibn Abi Talib (may Allah be pleased with him). She is the paternal aunt of the Messenger (peace and blessings be upon him). In the year of the Conquest, when the Prophet (peace and blessings be upon him) entered Makkah, he said: “Whoever enters the house of al-Abbas ibn 'Abd al-Muttalib is safe.” A man entered the house of Umm Hani, so she said to the Prophet (peace and blessings be upon him): “I have granted safety to this man.” He said: “We have granted safety to the one you granted safety, O Umm Hani.” Yes.
