Jami` at-Tirmidhi Book 49, Hadith 64
that the Messenger of Allah (ﷺ) used to go out to his Companions from The Muhajirin and the Ansar while they were sitting, and Abu Bakr and 'Umar would be with them. No one would lift their sight towards him except Abu Bakr and 'Umar, because they used to look at him, and he would look at them, and they would smile at him, and he would smile at them.
that Abu Bakr said: "Am I not the most deserving of it among the people, am I not the first to become Muslim, am I not the person of such and such, am I not the person of such and such."
that the Messenger of Allah (ﷺ) departed one day and entered the Masjid, along with Abu Bakr and 'Umar. One was on his right and the other was on his left, and he was holding their hands, and he said: "This is how we will be resurrected on the Day of Judgement.'"
