[Machine] The Messenger of Allah ﷺ used to come to us after the prayer was established, and he would wipe our shoulders and say, "Arrange your rows and do not differ, for your hearts may differ. Let those among you who have knowledge and authority lead, and beautify the Quran with your voices. Indeed, Allah and His angels send blessings upon the front line."  

كَانَ رَسُولُ اللَّهِ ﷺ يَأْتِينَا إِذَا أُقِيمَتِ الصَّلَاةُ فَيَمْسَحُ عَوَاتِقَنَا وَيَقُولُ «أَقِيمُوا صُفُوفَكُمْ وَلَا تَخْتَلِفُوا فَتَخْتَلِفَ قُلُوبُكُمْ وَلْيَلِيَنِّي مِنْكُمْ أُولُو الْأَحْلَامِ وَالنُّهَى وَزَيِّنُوا الْقُرْآنَ بِأَصْوَاتِكُمْ إِنَّ اللَّهَ وَمَلَائِكَتَهُ يُصَلُّونَ عَلَى الصَّفِّ الْمُقَدَّمِ»
