Jami` at-Tirmidhi Book 49, Hadith 63
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 Prophet (ﷺ) said: "Abu Bakr and 'Umar are the masters of the elder people among the inhabitants of Paradise, from the first ones and the last ones, not including the Prophets and the Messengers. Do not inform them O 'Ali."
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.
