Uthman bin Affan reported,

He has a nephew who met the Messenger of Allah ﷺ. I said to him, "No, but there has reached me of knowledge and certainty what reaches a virgin behind her veil."He gave the testimony of faith, then said, "To proceed. Allah عز وجل sent Muhammad ﷺ with the truth, and I was among those who responded to Allah and His Messenger and believed in what Muhammad ﷺ was sent with. Then I made the two migrations, as you said, and I attained the honor of becoming a son-in-law of the Messenger of Allah ﷺ, and I gave my pledge of allegiance to the Messenger of Allah ﷺ. By Allah, I never disobeyed him nor deceived him until Allah عز وجل took him in death."

عثمان بن عفان رضي الله عنه قال

له ابن أخي أدركت رسول الله ﷺ قال فقلت له لا ولكن خلص إلي من علمه واليقين ما يخلص إلى العذراء في سترها قال فتشهد ثم قال أما بعد فإن الله عز وجل بعث محمدا ﷺ بالحق فكنت ممن استجاب لله ولرسوله وآمن بما بعث به محمد ﷺ ثم هاجرت الهجرتين كما قلت ونلت صهر رسول الله ﷺ وبايعت رسول الله ﷺ فوالله ما عصيته ولا غششته حتى توفاه الله عز وجل
