The same hadith of the Holy Prophet (ﷺ) (may peace and blessings be upon him) has been reported by Abu Sa'id al-Khudri in connection with the story of Marwan.

Abu Mas'ud al-Ansari reported Allah's Messenger (ﷺ) as saying: The one who is most versed in Allah's Book should act as Imam for the people, but if they are equally versed in reciting it, then the one who has most knowledge regarding Sunnah; if they are equal regarding the Sunnah, then the earliest one to emigrate; it they emigrated at the same time, then the earliest one to embrace Islam. No man must lead another in prayer where (the latter) has authority, or sit in his place of honour in his house, without his permission. Ashajj in his narration used the word, "age" in place of "Islam".

Abu Mas'ud al-Ansari reported: The Messenger of Allah (ﷺ) said to us: The one who is well grounded in Allah's Book and is distinguished among them in recitation should act as Imam for the people. and if they are equally versed in reciting it, then the one who has most knowledge regarding Sunnah; if they are equal regarding the Sunnah, then the earliest one to emigrate; If they emigrated at the same time, then the oldest one in age. No man must lead another in prayer in latter's house or where (the latter) has authority, or sit in his place of honour in his house, except that he gives you permission or with his permission.

'Abdullah bin Mas'ud reported Allah's Messenger (ﷺ) as saying: If I were to choose a bosom friend I would have definitely chosen Abu Bakr (RA) 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 (ﷺ) himself) as a friend.
