4) Chapter: Those who are older going forward (to lead the prayer)
It was narrated that Milik bin Al-Huwairith said:
"I came to the Messenger of Allih (ﷺ) with a cousin of mine" - once he said, "with afriend of mine"-and he said: 'When you travel, call the Adhan and Iqamah, and let the older of you lead the prayer."'
4) باب تَقْدِيمِ ذَوِي السِّنِّ
أَخْبَرَنَا حَاجِبُ بْنُ سُلَيْمَانَ الْمَنْبِجِيُّ، عَنْ وَكِيعٍ، عَنْ سُفْيَانَ، عَنْ خَالِدٍ الْحَذَّاءِ، عَنْ أَبِي قِلاَبَةَ، عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ، قَالَ أَتَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم أَنَا وَابْنُ عَمٍّ لِي - وَقَالَ مَرَّةً أَنَا وَصَاحِبٌ لِي - فَقَالَ . " إِذَا سَافَرْتُمَا فَأَذِّنَا وَأَقِيمَا وَلْيَؤُمَّكُمَا أَكْبَرُكُمَا "
