Congregational Prayer and Its Virtue
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 57
وَقَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «أَفْسَدَ اِبْنُ مَسْعُودٍ عَلَى اَلنَّاسِ صَلاَتَهُمْ بِشَيْئَيْنِ بِقَوْلِهِ تَبَارَكَ اِسْمُكَ وتَعَالَى جَدُّكَ وَ هَذَا شَيْءٌ قَالَتْهُ اَلْجِنُّ بِجَهَالَةٍ فَحَكَاهُ اَللَّهُ تَعَالَى عَنْهَا وَ بِقَوْلِهِ اَلسَّلاَمُ عَلَيْنَا وَ عَلَى عِبَادِ اَللَّهِ اَلصَّالِحِينَ.
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "Ibn Mas'ud corrupted people's prayers with two things: by saying 'Blessed be Your Name, and Exalted is Your Majesty,' which was something the jinn said ignorantly, and Allah سبحانه وتعالى, the Exalted, narrated it from them, and by saying 'Peace be upon us and upon the righteous servants of Allah سبحانه وتعالى'."
