“The Messenger of Allah ﷺ said: ‘Will you not form your rows as the angels form their rows before their Lord?’ We said: ‘How do the angels form their rows before their Lord?’ He said: ‘They complete the first row and they stand close of one another in the line (leaving no gaps between one another).’”
قَالَ رَسُولُ اللَّهِ ﷺ أَلاَ تَصُفُّونَ كَمَا تَصُفُّ الْمَلاَئِكَةُ عِنْدَ رَبِّهَا قَالَ قُلْنَا وَكَيْفَ تَصُفُّ الْمَلاَئِكَةُ عِنْدَ رَبِّهَا قَالَ يُتِمُّونَ الصُّفُوفَ الأُوَلَ وَيَتَرَاصُّونَ فِي الصَّفِّ
