Uthman reported,

A man from Egypt came on pilgrimage to the House and saw a group of people sitting. He asked, "Who are these people?"They said, "These are Quraysh."He asked, "Who is the elder among them?"They said, "Abdullah bin Umar."He said, "Ibn Umar, I want to ask you about something, so tell me. Do you know that Uthman fled on the day of Uhud?"Ibn Umar replied, "Yes."The man said, "And do you know that he was absent from Badr and did not witness it?"Ibn Umar replied, "Yes."The man said, "And do you know that he was absent from the Pledge of Ridwan and did not witness it?"Ibn Umar replied, "Yes."The man exclaimed, "Allahu akbar!"Ibn Umar said, "Come, let me explain it to you. As for his fleeing on the day of Uhud, I bear witness that Allah has pardoned him and forgiven him. As for his absence from Badr, he was married to the daughter of the Messenger of Allah ﷺ, and she was ill, so the Messenger of Allah ﷺ said to him, 'You will have the reward of one who witnessed Badr and his share of the spoils.' As for his absence from the Pledge of Ridwan, if there had been anyone in Mecca more honored than Uthman, the Messenger of Allah ﷺ would have sent him in his place. So the Messenger of Allah ﷺ sent Uthman, and the Pledge of Ridwan took place after Uthman had gone to Mecca. The Messenger of Allah ﷺ held out his right hand and said, 'This is the hand of Uthman,' then he struck it upon his other hand and said, 'This is for Uthman.'"Then Ibn Umar said to the man, "Now take this answer with you."Musaddad narrated to us, Yahya narrated to us from Saeed from Qatada that Anas told them, "The Prophet ﷺ climbed Uhud, and with him were Abu Bakr, Umar, and Uthman. The mountain trembled, and he said, 'Be still, Uhud,'" — Anas thought he struck it with his foot — "'for upon you are none but a prophet, a truthful one, and two martyrs.'"
