Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 57
وَقَالَ أَبُو اَلْحَسَنِ مُوسَى بْنُ جَعْفَرٍ عَلَيْهِمَا اَلسَّلاَمُ: «إِنَّ اَلصَّلاَةَ فِي اَلصَّفِّ اَلْأَوَّلِ كَالْجِهَادِ فِي سَبِيلِ اَللَّهِ عَزَّ وَ جَلَّ.
Abu Al-Hasan Imam Musa ibn Jafar Al-Kadhim عليه السلام said: "Praying in the first row is like striving (jihad) in the way of Allah سبحانه وتعالى, the Mighty and Majestic."
