Who is most deserving of leading the Prayer
حَدَّثَنَا بِشْرُ بْنُ هِلاَلٍ الصَّوَّافُ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ خَالِدٍ الْحَذَّاءِ، عَنْ أَبِي قِلاَبَةَ، عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ، قَالَ أَتَيْتُ النَّبِيَّ ـ صلى الله عليه وسلم ـ أَنَا وَصَاحِبٌ لِي فَلَمَّا أَرَدْنَا الاِنْصِرَافَ قَالَ لَنَا " إِذَا حَضَرَتِ الصَّلاَةُ فَأَذِّنَا وَأَقِيمَا، وَلْيَؤُمَّكُمَا أَكْبَرُكُمَا " .
It was narrated that Malik bin Huwairith said: “I came to the Prophet (ﷺ) with a friend of mine, and when we wanted to leave, he said to us: ‘When the time for prayer comes, say the Adhan and Iqamah, then let the older of you lead the prayer.’”
