Congregational Prayer and Its Virtue
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 57
وَ رَوَى زُرَارَةُ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: «إِنَّ آخِرَ صَلاَةٍ صَلاَّهَا رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ بِالنَّاسِ فِي ثَوْبٍ وَاحِدٍ قَدْ خَالَفَ بَيْنَ طَرَفَيْهِ أَ لاَ أُرِيكَ اَلثَّوْبَ» قُلْتُ بَلَى قَالَ فَأَخْرَجَ مِلْحَفَةً فَذَرَعْتُهَا وَ كَانَتْ سَبْعَةَ أَذْرُعٍ فِي ثَمَانِيَةِ أَشْبَارٍ.
Zurarah narrated from Imam Muhammad ibn Ali Al-Baqir عليه السلام that He said: "The last prayer that the Messenger of Allah صلى الله عليه وعلى آله وسلم led the people in was while wearing a single garment, with its ends crossed over one another. Shall I show you the garment?" I said: "Yes." He then brought out a cloak, and I measured it—it was seven cubits by eight hand spans.
