Sahih Muslim , Hadith 673 ⓘ

Abu Mas'ud al-Ansari reported Allah's Messenger 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".

وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَأَبُو سَعِيدٍ الأَشَجُّ كِلاَهُمَا عَنْ أَبِي خَالِدٍ، - قَالَ أَبُو بَكْرٍ حَدَّثَنَا أَبُو خَالِدٍ الأَحْمَرُ، - عَنِ الأَعْمَشِ، عَنْ إِسْمَاعِيلَ بْنِ رَجَاءٍ، عَنْ أَوْسِ بْنِ ضَمْعَجٍ، عَنْ أَبِي مَسْعُودٍ الأَنْصَارِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ يَؤُمُّ الْقَوْمَ أَقْرَؤُهُمْ لِكِتَابِ اللَّهِ فَإِنْ كَانُوا فِي الْقِرَاءَةِ سَوَاءً فَأَعْلَمُهُمْ بِالسُّنَّةِ فَإِنْ كَانُوا فِي السُّنَّةِ سَوَاءً فَأَقْدَمُهُمْ هِجْرَةً فَإِنْ كَانُوا فِي الْهِجْرَةِ سَوَاءً فَأَقْدَمُهُمْ سِلْمًا وَلاَ يَؤُمَّنَّ الرَّجُلُ الرَّجُلَ فِي سُلْطَانِهِ وَلاَ يَقْعُدْ فِي بَيْتِهِ عَلَى تَكْرِمَتِهِ إِلاَّ بِإِذْنِهِ ‏" ‏ ‏.‏ قَالَ الأَشَجُّ فِي رِوَايَتِهِ مَكَانَ سِلْمًا سِنًّا ‏.‏

A hadith like this has been narrated by A'mash by the same chain of transmitters

حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، ح وَحَدَّثَنَا إِسْحَاقُ، أَخْبَرَنَا جَرِيرٌ، وَأَبُو مُعَاوِيَةَ ح وَحَدَّثَنَا الأَشَجُّ، حَدَّثَنَا ابْنُ فُضَيْلٍ، ح وَحَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا سُفْيَانُ، كُلُّهُمْ عَنِ الأَعْمَشِ، بِهَذَا الإِسْنَادِ مِثْلَهُ ‏.‏

Abu Mas'ud al-Ansari reported: The Messenger of Allah 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.

وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالَ ابْنُ الْمُثَنَّى حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، عَنْ شُعْبَةَ، عَنْ إِسْمَاعِيلَ بْنِ رَجَاءٍ، قَالَ سَمِعْتُ أَوْسَ بْنَ ضَمْعَجٍ، يَقُولُ سَمِعْتُ أَبَا مَسْعُودٍ، يَقُولُ قَالَ لَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ يَؤُمُّ الْقَوْمَ أَقْرَؤُهُمْ لِكِتَابِ اللَّهِ وَأَقْدَمُهُمْ قِرَاءَةً فَإِنْ كَانَتْ قِرَاءَتُهُمْ سَوَاءً فَلْيَؤُمَّهُمْ أَقْدَمُهُمْ هِجْرَةً فَإِنْ كَانُوا فِي الْهِجْرَةِ سَوَاءً فَلْيَؤُمَّهُمْ أَكْبَرُهُمْ سِنًّا وَلاَ تَؤُمَّنَّ الرَّجُلَ فِي أَهْلِهِ وَلاَ فِي سُلْطَانِهِ وَلاَ تَجْلِسْ عَلَى تَكْرِمَتِهِ فِي بَيْتِهِ إِلاَّ أَنْ يَأْذَنَ لَكَ أَوْ بِإِذْنِهِ ‏" ‏ ‏.‏
