question #2 Sahih al-Bukhari 3927, Book 63, Hadith 152 : How did Uthman demonstrate his loyalty and obedience to the Prophet Muhammad throughout his life?

I went to `Uthman. After reciting Tashah-hud, he said,. “Then after no doubt, Allah sent Muhammad
with the Truth, and I was amongst those who responded to the Call of Allah and His Prophet and
believed in the message of Muhammad. Then took part in the two migrations. I became the son-in-law
of Allah’s Messenger (ﷺ) and gave the pledge of allegiance to him By Allah, I never disobeyed him, nor did I
deceive him till Allah took him unto Him.”
