Sahih Muslim , Book 5, Hadith 374 (In-Book) ⓘ
Malik b Huwairith reported: I came to the Messenger of Allah 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.
وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ الْحَنْظَلِيُّ، أَخْبَرَنَا عَبْدُ الْوَهَّابِ الثَّقَفِيُّ، عَنْ خَالِدٍ الْحَذَّاءِ، عَنْ أَبِي قِلاَبَةَ، عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ، قَالَ أَتَيْتُ النَّبِيَّ صلى الله عليه وسلم أَنَا وَصَاحِبٌ لِي فَلَمَّا أَرَدْنَا الإِقْفَالَ مِنْ عِنْدِهِ قَالَ لَنَا " إِذَا حَضَرَتِ الصَّلاَةُ فَأَذِّنَا ثُمَّ أَقِيمَا وَلْيَؤُمَّكُمَا أَكْبَرُكُمَا " .
