The Book of Virtues
The Excellence of Standing in the First Row (In Salat)
وَعَنْ أَنَسٍ، رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: "سَوُّوا صُفُوفَكُمْ، فَإِنَّ تَسْوِيَةَ الصَّفِّ مِنْ تَمَامِ الصَّلاَةِ". ((مُتَّفَقٌ عَلَيْهِ)) وَفِي رِوَايَةٍ الْبُخَارِيّ: "فَإِنَّ تَسْوِيَةَ الصُّفُوفِ مِنْ إِقَامَةِ الصَّلاَةِ".
Anas (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) said, "Keep your rows straight (during Salat in congregation), for keeping the rows straight is part of the perfection of Salat." [Al-Bukhari and Muslim].
