Safiyyah's question to the Prophet (SAW)

He said: Abul Hasan Ali b. Khalid al-Maraghi reported to me from Abul Qasim al- Hasan b. Ali al-Kufi, who reported from Ja'far b. Muhammad b. Marwan, who reported from his father, who reported from Masih b. Muhammad, who reported from Abu Ali b. Abu Umrah al-Khurasani, from Ishaq b. Ibrahim from Abu Ishaq al-Sabiee', who said:

We called upon Masrooq b. al-Ajda and found a guest who we did not know. They were having their meals; and then the guest observed that he was with the Prophet, peace be upon him and his progeny, at Hunayn. Just as he said that, we knew he was a companion of the Prophet, peace be upon him and his progeny. He said:

Then Safiyyah, daughter of Hay b. Akhtab (one of the wives of the Prophet) came to the Prophet, peace be upon him and his progeny, and said: "O messenger of Allah, I am not like your other wives who have father, brother and uncle. If anything were to happen to you, to who do you entrust me?"

The Prophet, peace be upon him and his progeny, pointing at Ali b. Abi Talib, peace be upon him said: "To him." Then he said: "May I not relate to you what al-Harith b. al-A'awar narrated to us?" We said: "Please do."

He said: I called upon Ali b. Abi Talib, peace be upon him and his progeny, and he asked: "O A'awar, what brings you here?" A'awar says he replied: "O Amirul Mo'mineen, your love has brought us." He asked: "Really?" I said: "Yes,Allah is my witness." He confirmed with me three times. 

Then he said: "There is no  slave of Allah who He has tested for piety, except that He finds our love in his heart; such a person indeed loves us. And there is no slave of Allah upon whom Allah has shown His displeasure, except that He finds our hatred in his heart, and such a person indeed hates us. 

So, our friends always expect the divine mercy, and the gates of mercy are open for them. And our enemies are upon the edge of crumbling bank that will tumble down with them in to the fire of hell. Bounteous is the mercy for the people who earn it, and perdition is for the people of hell fire."
