Straightening the rows at the time of Iqama and after it (immediately)
Sahih Bukhari
حَدَّثَنَا أَبُو مَعْمَرٍ، قَالَ حَدَّثَنَا عَبْدُ الْوَارِثِ، عَنْ عَبْدِ الْعَزِيزِ، عَنْ أَنَسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " أَقِيمُوا الصُّفُوفَ فَإِنِّي أَرَاكُمْ خَلْفَ ظَهْرِي ".
Narrated Anas: The Prophet (ﷺ) said, "Straighten your rows, for I see you from behind my back.'
