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.’”

حَدَّثَنَا بِشْرُ بْنُ هِلاَلٍ الصَّوَّافُ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ خَالِدٍ الْحَذَّاءِ، عَنْ أَبِي قِلاَبَةَ، عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ، قَالَ أَتَيْتُ النَّبِيَّ ﷺ أَنَا وَصَاحِبٌ لِي فَلَمَّا أَرَدْنَا الاِنْصِرَافَ قَالَ لَنَا " إِذَا حَضَرَتِ الصَّلاَةُ فَأَذِّنَا وَأَقِيمَا وَلْيَؤُمَّكُمَا أَكْبَرُكُمَا " .
