"Make your rows straight, make your rows straight, make your rows straight. By the One in Whose Hand is my soul! I can see you behind me as I can see you in front of me."  

أَنَّ النَّبِيَّ ﷺ كَانَ يَقُولُ اسْتَوُوا اسْتَوُوا اسْتَوُوا فَوَالَّذِي نَفْسِي بِيَدِهِ إِنِّي لأَرَاكُمْ مِنْ خَلْفِي كَمَا أَرَاكُمْ مِنْ بَيْنِ يَدَىَّ
