Anas b. Malik reported that Abu Bakr Siddiq reported him thus
I saw the feet of the polytheists very close to us as we were in the cave. I said: Allah's Messenger, if one amongst them were to see at his feet he would have surely seen us. Thereupon he said: Abu Bakr, what can befall two who have Allah as the third One with them.
Abu Sa'id reported that Allah's Messenger (ﷺ) sat on the pulpit and said
Allah gave a choice to His servant that he may opt the beauties of the world or that which is with Him and the servant chose that which was with Him. Thereupon Abu Bakr wept and he wept bitterly and said: Let our fathers and our mothers be taken as ransom for you. It was Allah's Messenger (ﷺ) who had been given the choice and Abu Bakr knew it better than us, and Allah's Messenger (ﷺ) is reported to have said: Behold, of all people the most generous toward me in regard to his companionship and his property was Abu Bakr and were I to choose anyone as my bosom friend, I would have chosen Abu Bakr as my dear friend, but (for him) I cherish Islamic brotherliness and love. There shall be left open no window in the mosque except Abu Bakr's window.
This hadith has been narrated on the authority of Abu Sa'id Khudri through another chain of transmitters.
'Abdullah b. Mas'ud reported Allah's Messenger (ﷺ) as saying
If I were to choose a bosom friend I would have definitely chosen Abu Bakr as my bosom friend, but he is my brother and my companion and Allah, the Exalted and Gliorious. has taken your brother and companion (meaning Prophet himself) as a friend.
Abdullah reported Allah's Messenger (ﷺ) as saying
If I were to choose from my Umma anyone as my bosom friend, I would have chosen Abu Bakr.
'Abdullah reported Allah's Messenger (ﷺ) as saying
If I were to choose as my bosom friend I would have chosen the son of Abu Quhafa (Abu Bakr) as my bosom friend.
Abdullah reported Allah's Messenger (ﷺ) as saying
If I were to choose amongst the people of earth someone as my bosom friend, I would have chosen the son of Abu Quhafa as my friends but God has taken your companion as a friend.
This hadith has been narrated through another chain of transmitters and the one narrated on the authority of Abdullah (the words are)
" Allah's Messenger (ﷺ) is reported to have said: Behold I am free from the dependence of all bosom friends and if I were to choose anyone as bosom friend I would have taken Abu Bakr as my bosom friend. Allah has taken your companion as a friend.
'Amr b. al-'As reported that Allah's Messenger (ﷺ) sent him in command of the army despatched to Dhat-as-Salasil. When 'Amr b. al-'As came back to the Prophet (ﷺ) he said
Who amongst people are dearest to you? He said: A'isha. He then said: Who amongst men? He said: Her father, and I said: And who next? He said: Umar. He then enumerated some other men.
Ibn Abu Mulaika reported
I heard `A'isha as saying and she was asked as to whom Allah's Messenger (ﷺ) would have nominated as his successor if he had to nominate one at all. She said: Abu Bakr. It was said to her: Then whom after Abu Bakr? She said: `Umar. It was said to her. Then whom after `Umar? She said: Abu `Ubaida b. al-Jarrah, and then she kept quiet at this.
Muhammad b. Jubair b. Mut'im reported on the authority of his father that a woman asked Allah's Messenger (ﷺ) about something but lit, told her to come to him on some other occasion, whereupon she said
What in your opinion (should I do) if I come to you but do not find you , and it seemed as if she meant that he might die. Thereupon he said : If you do not find me , then come to Abu Bakr.
This hadith has been narrated on the authority of Jubair b. Mut'im through another chain of transmitters (and the words are) that a woman came to Allah's Messenger (ﷺ) and discussed with him something and he gave a command as we find in the above-mentioned narration.
A'isha reported that Allah's Messenger (ﷺ) in his (last) illness asked me to call Abu Bakr, her father, and her brother too, so that he might write a document, for he feared that someone else might be desirous (of succeeding him) and that some claimant may say
I have better claim to it, whereas Allah and the Faithful do not substantiate the claim of anyone but that of Abu Bakr.
Abu Huraira reported that Allah's Messenger (ﷺ) said
Who amongst you is fasting today? Abu Bakr said: I am. He (again) said: Who amongst you followed a funeral procession today? Abu Bakr said: I did. He (the Prophet) again said: Who amongst you served food to the needy? Abu Bakr said: I did. He (again) said: Who amongst you has today visited the sick? Abu Bakr said: I did. Thereupon Allah's Messenger (ﷺ) said: Anyone in whom (these good deeds) are combined will certainly enter paradise.
Abu Huraira reported Allah's Messenger (ﷺ) as saying
A person had been driving an ox loaded with luggage. The ox looked towards him and said: I have not been created for this but for lands (i. e. for ploughing the land and for drawing out water from the wells for the purpose of irrigating the lands). The people said with surprise and awe: Hallowed be Allah, does the ox speak? Allah's Messenger (ﷺ) said: I believe it and so do Abu Bakr and 'Umar. Abu Huraira reported Allah's Messenger (ﷺ) as saying: A shepherd was tendirig the flock when a wolf came there and took away one goat. Tile shepherd pursued it (the wolf) and rescued it (the goat) from that (wolf). The wolf looked towards him and said: Who would save it on the day when there will be no shepherd except me? Thereupon people said: Hallowed be Allah I Thereupon Allah's Messenger (ﷺ) said: I believe in it and so do Abu Bakr and Umar believe.
This hadith has been narrated on the authority of Ibn Shihab with the same chain of transmitters, but there is no mention of the story pertaining to the ox.
This hadith has been transmitted on the authority of Zuhri, and there is a clear mention of the stories of ox and goat (and the words are)
