[Machine] The Messenger of Allah ﷺ said, "When you are with your companion, give the call to prayer (adhan) and establish the prayer (iqamah), and let the one who knows more of the Quran lead you in prayer."
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «إِذَا كُنْتَ مَعَ صَاحِبِكَ فَأَذِّنْ وَأَقِمْ وَلْيَؤُمَّكُمَا أَكْبَرُكُمَا»
Prophet said (to two persons), "Whenever the prayer time becomes due, you should pronounce Adhan and then Iqama and the older of you should lead the prayer."
عَنِ النَّبِيِّ ﷺ قَالَ إِذَا حَضَرَتِ الصَّلاَةُ فَأَذِّنَا وَأَقِيمَا ثُمَّ لِيَؤُمَّكُمَا أَكْبَرُكُمَا
On my departure from the Prophet ﷺ he said to me and to a friend of mine, "You two, pronounce the Adhan and the Iqama for the prayer and let the elder of you lead the prayer."
انْصَرَفْتُ مِنْ عِنْدِ النَّبِيِّ ﷺ فَقَالَ لَنَا أَنَا وَصَاحِبٌ لِي أَذِّنَا وَأَقِيمَا وَلْيَؤُمَّكُمَا أَكْبَرُكُمَا
"I came to the Prophet ﷺ with a cousin of mine" - on an another occasion he said: "with a companion of mine" - "and he said: 'When the two of you travel, call the Adhan and the Iqamah, and let the older of you lead the prayer.'" (Using translation from Nasāʾī 634)
أَتَيْتُ النَّبِيَّ ﷺ أَنَا وَصَاحِبٌ لِي فَقَالَ «إِذَا صَلَّيْتُمَا فَأَذِّنَا وَأَقِيمَا وَلْيَؤُمَّكُمَا أَكْبَرُكُمَا»
"The Messenger of Allah ﷺ said to me and to a companion of mine: 'When the time for prayer comes, let the two of you call the Adhan then the two of you say Iqamah, then let one of you lead the prayer.'" (Using translation from Nasāʾī 669)
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لَهُ وَلِصَاحِبٍ لَهُ «إِذَا حَضَرَتِ الصَّلَاةُ فَأَذِّنَا ثُمَّ أَقِيمَا ثُمَّ لِيَؤُمَّكُمَا أَكْبَرُكُمَا»
"إذا سافْرتُما فأذِّنا وأقيما وليؤمكما أكبرُكُمَا".
