Musnad Ahmad #450

`Uthman bin `Affan (رضي الله عنه) said to his nephew: Did you meet the Messenger of Allah (ﷺ)? He said: No, but there reached me of his knowledge and certainty of faith that which would reach a virgin in her seclusion .He recited the tashahhud then he said: Verily Allah, may He be glorified and exalted, sent Muhammad with the truth and I was one of those who responded to (the call of) Allah and His Messenger, and I believed in that with which Muhammad (ﷺ) was sent. Then I migrated twice, and I also attained the honour of becoming the son-in law of the Messenger of Allah (ﷺ), I swore allegiance to the Messenger of Allah (ﷺ), and by Allah, I never disobeyed him or betrayed him until Allah, may He be glorified and exalted, took his soul in death.
