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. (Using translation from Muslim 674d)
أَتَيْتُ النَّبِيَّ ﷺ أَنَا وَصَاحِبٌ لِي فَلَمَّا أَرَدْنَا الْإِقْفَالَ مِنْ عِنْدِهِ قَالَ لَنَا إِذَا حَضَرَتِ الصَّلَاةُ فَأَذِّنَا ثُمَّ أَقِيمَا وَلْيَؤُمَّكُمَا أَكْبَرُكُمَا
