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". (Using translation from Muslim 673a)   

قَالَ رَسُولُ اللهِ ﷺ يَؤُمُّ الْقَوْمَ أَقْرَؤُهُمْ لِكِتَابِ اللهِ فَإِنْ كَانُوا فِي الْقِرَاءَةِ سَوَاءً فَأَعْلَمُهُمْ بِالسُّنَّةِ فَإِنْ كَانُوا فِي السُّنَّةِ سَوَاءً فَأَقْدَمُهُمْ هِجْرَةً فَإِنْ كَانُوا فِي الْهِجْرَةِ سَوَاءً فَأَكْبَرُهُمْ سِنًّا وَلَا يُؤَمُّ رَجُلٌ فِي سُلْطَانِهِ وَلَا يُجْلَسُ عَلَى تَكْرِمَتِهِ فِي بَيْتِهِ إِلَّا بِإِذْنِهِ  

[Machine] The Messenger of Allah ﷺ said, "He who leads the people in prayer should be the one who knows the Qur'an the most. If they are equal in recitation of the Qur'an, then the one who migrated earlier should lead them. If they are equal in migration, then the one who has more understanding of the religion should lead them. If they are equal in religious understanding, then the eldest among them should lead. No man should be appointed leader over his own authority or sit on his own honor without permission." This was narrated by Jarir ibn Hazim from Al-A'mash, and it was narrated by a group from Al-A'mash with the same wording.  

قَالَ رَسُولُ اللهِ ﷺ يَؤُمُّ الْقَوْمَ أَكْثَرُهُمْ قُرْآنًا فَإِنْ كَانُوا فِي الْقُرْآنِ وَاحِدًا فَأَقْدَمُهُمْ هِجْرَةً فَإِنْ كَانَتِ الْهِجْرَةُ وَاحِدَةً فَأَكْثَرُهُمْ فِقْهًا فَإِنْ كَانَ الْفِقْهُ وَاحِدًا فَأَكْبَرُهُمْ سِنًّا وَلَا يُؤَمَّنَّ رَجُلٌ فِي سُلْطَانِهِ وَلَا يُجْلَسُ عَلَى تَكْرِمَتِهِ فِي بَيْتِهِ إِلَّا أَنْ يَأْذَنَ لَهُ كَذَا قَالَهُ جَرِيرُ بْنُ حَازِمٍ عَنِ الْأَعْمَشِ وَرَوَاهُ جَمَاعَةٌ عَنِ الْأَعْمَشِ عَلَى اللَّفْظِ الْأَوَّلِ  

[Machine] The Messenger of Allah ﷺ said, "When they are three, one of them should lead them in prayer, and the most knowledgeable of them in recitation should lead them."  

قَالَ رَسُولُ اللهِ ﷺ إِذَا كَانُوا ثَلَاثَةً فَلْيَؤُمَّهُمْ أَحَدُهُمْ وَأَحَقُّهُمْ بِالْإِمَامَةِ أَقْرَؤُهُمْ لَفْظُهُمَا سَوَاءٌ  

[Machine] "That the Prophet ﷺ said: When there are three in a journey, let one of them lead the prayer and the most deserving among them for leadership is the one who is most knowledgeable in reciting the Quran."  

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا كَانُوا ثَلَاثَةً فِي سَفَرٍ فَلْيَؤُمَّهُمْ أَحَدُهُمْ وَأَحَقُّهُمْ بِالْإِمَامَةِ أَقْرَؤُهُمْ
