Abu Salamah bin Abdur Rahman narrates that Sayyiduna Uthman (may Allah be pleased with him) looked out from his house, while he was besieged, and said: "I ask you by Allah's name, who was present at that time when the Prophet (peace and blessings be upon him) was on Mount Hira, and the mountain began to shake, so the Prophet (peace and blessings be upon him) struck it with his foot and said: 'O Hira! Be still, for upon you is a Prophet, a Siddiq, and a martyr.' I was also with the Prophet (peace and blessings be upon him) at that time." So some people testified to this (that it was true). Then Sayyiduna Uthman (may Allah be pleased with him) said: "Whoever was present with the Prophet (peace and blessings be upon him) at the time of the pledge of Ridwan, I ask him by Allah's name, when the Prophet (peace and blessings be upon him) sent me to the polytheists, did he not say: 'This is my hand and this is Uthman's hand.' Then the Prophet (peace and blessings be upon him) took the pledge on my behalf." Some people also confirmed this statement of his. Then Sayyiduna Uthman (may Allah be pleased with him) said: "I ask by Allah's name the one who was present when the Prophet (peace and blessings be upon him) said: 'Who will buy this house and add it to the mosque, and in return he will have a house in Paradise?' So I bought that house from my wealth and expanded the mosque with it." Some people confirmed this statement of his as well. Then Sayyiduna Uthman (may Allah be pleased with him) said: "I ask by Allah's name the one who was present when the Prophet (peace and blessings be upon him) was preparing for the Battle of Tabuk, and he said: 'Who will spend today in a way that will be accepted?' So I provided half of the army's equipment from my wealth." Some people also confirmed this statement of his. Then Sayyiduna Uthman (may Allah be pleased with him) said: "I ask by Allah's name the one who was present when the water of Rumah was sold only to travelers, so I bought it from my wealth and dedicated it for the travelers (and for all Muslims)." So some people also confirmed this statement of his.
