Jami` at-Tirmidhi Book 49, Hadith 97
that 'Uthman went to the Prophet (ﷺ) with one-thousand Dinar" - Al-Hasan bin Waqi (one of the narrators) said: "And in another place in my book: 'In his garment when the 'army of distress' was being prepared. So he poured them into his lap.'" - 'Abdur-Rahman said: "So I saw the Prophet (ﷺ) turning them over in his lap, saying: 'Whatever 'Uthman does after today will not harm him,' two times."
"I witnessed the Prophet (ﷺ) while he was exhorting support for the 'army of distress.' 'Uthman bin 'Affan stood and said: 'O Messenger of Allah! I will take the responsibility of one-hundred camels, including their saddles and water-skins, in the path of Allah.' Then he I will take the responsibility of three-hundred camels, including their saddles and water-skins, in the path of Allah.' So I saw the Messenger of Allah (ﷺ) descend from the Minbar while he was saying: 'It does not matter what 'Uthman does after this, it does not matter what 'Uthman does after this.'"
that when the Messenger of Allah (ﷺ) ordered the pledge of Ridwan, 'Uthman bin 'Affan was the messenger of the Messenger of Allah (ﷺ) to the people of Makkah. He said: "So the people gave the pledge." He said: "So the Messenger of Allah (ﷺ) said: 'Indeed 'Uthman is busy with the affair of Allah and the affair of His Messenger' then he (ﷺ) put one of his hands on the other. The hand of the Messenger of Allah (ﷺ) on behalf of 'Uthman, was better than their own hands for themselves.
