(وَعَنْهُ أَيْضًا قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((أَقِيمُوا صُفُوفَكُمْ فَإِنَّ مِنْ حُسْنِ الصَّلَاةِ إِقَامَةَ الصَّفِّ))
Sayyiduna Anas (may Allah be pleased with him) also narrates that the Messenger of Allah (peace and blessings be upon him) said: Straighten your rows, for indeed straightening the row is part of the beauty of prayer.
