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

Hedîs 1535 — صحيح مسلم 5:368
وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا أَيُّوبُ، عَنْ أَبِي قِلاَبَةَ، عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ، قَالَ أَتَيْنَا رَسُولَ اللَّهِ صلى الله عليه وسلم وَنَحْنُ شَبَبَةٌ مُتَقَارِبُونَ فَأَقَمْنَا عِنْدَهُ عِشْرِينَ لَيْلَةً وَكَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم رَحِيمًا رَقِيقًا فَظَنَّ أَنَّا قَدِ اشْتَقْنَا أَهْلَنَا فَسَأَلَنَا عَنْ مَنْ تَرَكْنَا مِنْ أَهْلِنَا فَأَخْبَرْنَاهُ فَقَالَ " ارْجِعُوا إِلَى أَهْلِيكُمْ فَأَقِيمُوا فِيهِمْ وَعَلِّمُوهُمْ وَمُرُوهُمْ فَإِذَا حَضَرَتِ الصَّلاَةُ فَلْيُؤَذِّنْ لَكُمْ أَحَدُكُمْ ثُمَّ لْيَؤُمَّكُمْ أَكْبَرُكُمْ " .
Malik b. Huwairith reported:We came to the Messenger of Allah (ﷺ) and we were all young men of nearly equal age. We stayed with him (the Holy Prophet) for twenty nights, and as the Messenger of Allah (ﷺ) was extremely kind and tender of heart, he therefore, thought that we were eager (to see) our family (we felt homesick). So he asked us about the members of the family that we had left behind and when we informed him, he said: Go back to your family, stay with them, and teach them (beliefs and practices of Islam) and exhort them to good, and when the time for prayer comes, one amongst you should announce Adhan and then the oldest among you should lead the prayer
Malik b. Huwairith Abu Sulaiman reported:I came to the Messenger of Allah (ﷺ) along with other persons and we were young men of nearly equal age, and the rest of the hadith was transmitted like the hadith narrated before
Malik b Huwairith reported:I came to the Messenger of Allah (ﷺ) along with a companion of mine, and when we intended to return from him, he said: When there is time for prayer, announce prayer, pronounce Iqama, and the oldest amongst you should lead the prayer
Abu Salama b. Abd al-Rahman b. 'Auf heard Abu Huraira say:(When) Allah's Messenger (ﷺ) (wished to invoke curse or blessing on someone, he would do so at the end) of the recitation in the dawn prayer, when he had pronounced Allah-o-Akbar (for bending) and then lifted his head (saying):" Allah listened to him who praised Him; our Lord! to Thee is all praise" ; he would then stand up and say:" Rescue al-Walid b. Walid, Salama b. Hisham, and 'Ayyash b. Abd Rabi'a, and the helpless among the Muslims. O Allah! trample severely Mudar and cause them a famine (which broke out at the time) of Joseph. O Allah! curse Lihyan, Ri'l, Dhakwan, 'Usayya, for they disobeyed Allah and His Messenger." (The narrator then adds): The news reached us that he abandoned (this) when this verse was revealed:" Thou but no concern in the matter whether He turns to them (mercifully) or chastises them; surely they are wrongdoers" (ill)
