Musnad Ahmad Hadith 420

`Uthman (رضي الله عنه) looked out from the house when he was under siege and said: I adjure by Allah anyone who was present with the Messenger of Allah (ﷺ) , on the day of Hira`, when the mountain shook beneath his feet; he kicked it with his foot and said: “Be still, Hira`, there is no one on you but a Prophet, a Siddiq or a martyr,` and i was with him. And some men testified to what he said. Then he said: I adjure by Allah anyone who was present with the Messenger of Allah (ﷺ) on the day of Bai’atul-Ridwan, when he had sent me to the mushrikeen, the people of Makkah; he said, `This is my hand and this is the hand of `Uthman,` and he swore allegiance on my behalf. And some men testified to what he said. Then he said:l adjure by Allah anyone who was present when the Messenger of Allah (ﷺ) said: `Who will expand the mosque by incorporating this house into it, in return for a house in Paradise?” and I bought it with my wealth and expanded the mosque by incorporating it into it. And some men testified to what he said. Then he said: I adjure by Allah anyone who saw the Messenger of Allah (ﷺ) on the day of the army of hardship (i.e., Tabook), when he said: `Who will spend today a spending that will be accepted by Allah?` and I equipped half of the army with my wealth. And some men testified to what he said, Then he said:I adjure by Allah anyone who saw the water of Roomah (a well) being sold to wayfarers, then I bought it with my own wealth and gave it to wayfarers for free.` And some men testified to what he said.
