٥ـ عَلِيُّ بْنُ مُحَمَّدٍ عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ أَبِي هَاشِمٍ الْجَعْفَرِيِّ قَالَ كُنْتُ مَعَ أَبِي الْحَسَنِ (عَلَيْهِ الْسَّلام) فِي السَّفِينَةِ فِي دِجْلَةَ فَحَضَرَتِ الصَّلاَةُ فَقُلْتُ جُعِلْتُ فِدَاكَ نُصَلِّي فِي جَمَاعَةٍ قَالَ فَقَالَ لاَ تُصَلِّ فِي بَطْنِ وَادٍ جَمَاعَةً. 
5. Ali ibn Muhammad has narrated from Sahl ibn Ziyad from abu Hashim al-Ja‘fariy who has said the following: “One abu al-Hassan , and I were in a ship on the Tigris. It became time for Salah (prayer) and I said, ‘I pray to Allah to keep my soul in service for your cause, can we perform Salah (prayer) in congregation? He (the Imam) said, ‘No, we perform Salah (prayer) in the valley in congregation.’”
