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."
Sahih al-Bukhari Book 63, Hadith 152
← Previous Hadith When Allah's Messenger (ﷺ) came to Medina, Abu Bakr and Bilal got fever, and I went to both of them and said, "O my father, how do you feel? O Bilal, how do you feel?" Whenever Abu Bakr's fever got worse, he would say, "Every man will meet his death once in one morning while he will be among his family, for death is really nearer to him than his leather shoe laces (to his feet)." And whenever fever deserted Bilal, he would say aloud, "Would that I know whether I shall spend a night in the valley (of Mecca) with Idhkhir and Jalil (i.e. kinds of grass) around me, and whether I shall drink one day the water of Mijannah, and whether I shall see once again the hills of Shamah and Tafil?" Then I went to Allah's Messenger (ﷺ) and told him of that. He said, "O Allah, make us love Medina as much as or more than we used to love Mecca, O Allah, make it healthy and bless its Sa' and Mud (i.e. measures), and take away its fever to Al-Juhfa."

Sahih al-Bukhari Book 63, Hadith 151 Next Hadith → During the last Hajj led by `Umar, `Abdur-Rahman bin `Auf returned to his family at Mina and met me there. `AbdurRahman said (to `Umar), "O chief of the believers! The season of Hajj is the season when there comes the scum of the people (besides the good amongst them), so I recommend that you should wait till you go back to Medina, for it is the place of Migration and Sunna (i.e. the Prophet's tradition), and there you will be able to refer the matter to the religious scholars and the nobles and the people of wise opinions." `Umar said, "I will speak of it in Medina on my very first sermon I will deliver there."
