Sahih al-Bukhari Book 62, Hadith 10
The people of Kufa sent a letter to Ibn Az-Zubair, asking about (the inheritance of) (paternal)
grandfather. He replied that the right of the inheritance of (paternal) grandfather is the same as that of
father if the father is dead) and added, "Allah's Messenger (ﷺ) said, ' If I were to take a Khalil from this
nation, I would have taken him (i.e. Abu Bakr).
The Prophet (ﷺ) said, "If I were to take a Khalil, I would have taken him (i.e. Abu Bakr) as a Khalil, but the Islamic brotherhood is better."
A woman came to the Prophet (ﷺ) who ordered her to return to him again. She said, "What if I came and did not find you?" as if she wanted to say, "If I found you dead?" The Prophet (ﷺ) said, "If you should not find me, go to Abu Bakr."
