Muhammad ibn Abi Bakr
Around the time of mid-day prayers, Uthman was alone inside the house with his wife Naila, reading the Qur'an. Some Egyptian rebels climbed the houses of the neighbors and then jumped into Uthman's. According to the account of al-Waqidi (d. 823), Muhammad ibn Abi Bakr held the beard of Uthman threatening to kill him. Uthman rebuked him and asked him to leave. Muhammad pierced his forehead with an arrow. However according to another report, Muhammad desisted from killing Uthman after the latter reminded him of his father Abu Bakr. Muhammad then vainly tried defending him from the attackers.
