Sahih Muslim Book - 5, Hadith - 1534

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 فِى الْهِجْرَةِ سَوَاءً فَلْيَؤُمَّهُمْ أَكْبَرُهُمْ سِنًّا وَلاَ تَؤُمَّنَّ الرَّجُلَ فِى أَهْلِهِ وَلاَ فِى سُلْطَانِهِ وَلاَ تَجْلِسْ عَلَى تَكْرِمَتِهِ فِى بَيْتِهِ إِلاَّ أَنْ يَأْذَنَ لَكَ أَوْ بِإِذْنِهِ ».

It was narrated that Isma'il bin Raja' said: "I heard 'Aws bin Dam'aj say: 'I heard Abu Mas'ud say: "The Messenger of Allah (s.a.w) said to us: 'The people should be led in prayer by the one who recites the most of the Book of Allah and who has been reciting it for longer. If they are equal in recitation (of the Qur'an), then they should be led by the one who emigrated earlier. If they are equal in terms of emigration, then they should be led by the one who is oldest. Do not lead a man in prayer among his family nor in his place of authority, and do not sit in his place of honor in his house, unless he gives you permission," or "with his permission."
