It was narrated from Abu Salamah bin 'Abdur-Rahman that 'Uthman looked out over them when they besieged him and said:
By Allah, I adjure a man who heard the Messenger of Allah, on the day when the mountain shook with him, and he kicked it with his foot and said: 'Be still, for there is no one upon you but a Prophet or a Siddiq or two martyrs,' and I was with him. Some men responded and affirmed that. Then he said: By Allah, I adjure a man who witnessed the Messenger of Allah, on the day of Bai'at Al-Ridwan, say: 'This is the Hand of Allah and this is the hand of 'Uthman.' Some men responded and affirmed that. He said: By Allah, I adjure a man who heard the Messenger of Allah say, on the day of the army of Al-'Usrah (i.e. Tabuk): 'Who will spend and it will be accepted?' And I equipped half of the army from my own wealth. Some men responded and affirmed that. Then he said: By Allah, I adjure a man who heard the Messenger of Allah say: 'Who will add to this Masjid in return for a house in Paradise,' and I bought it with my own wealth. Some men responded and affirmed that. Then he said: By Allah, I adjure a man who witness Rumah being sold, and I bought it from my own wealth and allowed wayfarers to use it. Some men responded and affirmed that.
