It is narrated from Sayyiduna Urwah bin Zubair (may Allah be pleased with him), he says: I asked Sayyiduna Abdullah bin Amr bin Aas (may Allah be pleased with them both): Tell me, what was the greatest harm that the polytheists caused to the Messenger of Allah (peace and blessings be upon him)? He said: The Messenger of Allah (peace and blessings be upon him) was performing prayer in the courtyard of the Ka'bah when Uqbah bin Abi Mu'it came there. He grabbed the shoulder of the Prophet (peace and blessings be upon him), put a cloth around his neck, twisted it, and strangled him severely. Sayyiduna Abu Bakr (may Allah be pleased with him) came forward, grabbed the wretch's shoulder, pulled him away from the Messenger of Allah (peace and blessings be upon him), and said: Do you kill a man because he says, "My Lord is Allah," and he has brought you clear signs from your Lord?
