It was narrated that An-Numan bin Bashir said:
"The Messenger of Allah ﷺ used to straighten the rows like shaft of an arrow is straightened before the head is attached to it. He saw a man whose chest was sticking out from the row. I saw the Messenger of Allah ﷺ say: 'Make your rows straight or Allah will cause your faces to be deformed."
أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ أَنْبَأَنَا أَبُو الأَحْوَصِ، عَنْ سِمَاكٍ، عَنِ النُّعْمَانِ بْنِ بَشِيرٍ، قَالَ كَانَ رَسُولُ اللَّهِ ﷺ يُقَوِّمُ الصُّفُوفَ كَمَا تُقَوَّمُ الْقِدَاحُ فَأَبْصَرَ رَجُلاً خَارِجًا صَدْرُهُ مِنَ الصَّفِّ فَلَقَدْ رَأَيْتُ النَّبِيَّ ﷺ يَقُولُ " لَتُقِيمُنَّ صُفُوفَكُمْ أَوْ لَيُخَالِفَنَّ اللَّهُ بَيْنَ وُجُوهِكُمْ " .

It was narrated that Al-Bara bin Azib said:
"The Messenger of Allah ﷺ used to go between the rows from one side to another, patting our shoulders and chests and saying: 'Do not make your rows ragged or your hearts will be filled with enmity toward one another.' And he used to say: 'Allah and His angels send Salah upon the front rows."'
أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ مَنْصُورٍ، عَنْ طَلْحَةَ بْنِ مُصَرِّفٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَوْسَجَةَ، عَنِ الْبَرَاءِ بْنِ عَازِبٍ، قَالَ كَانَ رَسُولُ اللَّهِ ﷺ يَتَخَلَّلُ الصُّفُوفَ مِنْ نَاحِيَةٍ إِلَى نَاحِيَةٍ يَمْسَحُ مَنَاكِبَنَا وَصُدُورَنَا وَيَقُولُ " لاَ تَخْتَلِفُوا فَتَخْتَلِفَ قُلُوبُكُمْ " . وَكَانَ يَقُولُ " إِنَّ اللَّهَ وَمَلاَئِكَتَهُ يُصَلُّونَ عَلَى الصُّفُوفِ الْمُتَقَدِّمَةِ " .
