I came to the Prophet ﷺ with some men from my tribe and stayed with him for twenty nights. He was kind and merciful to us. When he realized our longing for our families, he said to us, "Go back and stay with your families and teach them the religion, and offer the prayer and one of you should pronounce the Adhan for the prayer when its time is due and the oldest one amongst you should lead the prayer." (Using translation from Bukhārī 628)
أَتَيْتُ النَّبِيَّ ﷺ فِي نَفَرٍ مِنْ قَوْمِي فَأَقَمْنَا عِنْدَهُ عِشْرِينَ لَيْلَةً وَكَانَ رَحِيمًا رَقِيقًا فَلَمَّا رَأَى شَوْقَنَا إِلَى أَهْلِنَا قَالَ ارْجِعُوا فَكُونُوا فِيهِمْ وَعَلِّمُوهُمْ وَصَلُّوا فَإِذَا حَضَرَتِ الصَّلَاةُ فَلْيُؤَذِّنْ لَكُمْ أَحَدُكُمْ وَلْيَؤُمَّكُمْ أَكْبَرُكُمْ
