Anas رضي الله عنه said: “They beat Allah’s Messenger until he fainted. Abu Bakr came and started to shout and say: woe to you! Do you kill a man just because he says my Lord is Allah? They said: who is this? They replied: This is the son of Abu Quhaafah, the madman.”

Al-Haakim reported, in al-Mustadrak and said the isnad is sound according to the condition of Muslim to which the author of at-Talkhees agreed.
