He was a teacher of Muhammad Ibne Ismail Bukhari, author of the
most authentic book of Ahle Sunnat. Al-Musannaf
He has written in it :
When people paid allegiance to Abu Bakr, and Ali and Zubair entered
into a huddle in the house of Fatima, this information reached Umar bin
Khattab; he came to the house of Fatima and said: O daughter of the Messenger
of Allah, by Allah, your father was the most beloved person for us and after
him it was you; but by Allah this love will not prevent me from ordering the
burning down of this place along with its inmates if these people gather here.
Umar made this remark and went away. When Ali (a) and Zubair returned, the
honorable daughter of the Prophet said to Ali (a) and Zubair: Umar came and
swore that if you again hold a meeting here, he would burn down the house on
you; by Allah, he would indeed do what he has sworn.[1]
