3ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنِ ابْنِ مَحْبُوبٍ عَنِ الْعَلاءِ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ (عَلَيهِ السَّلام) قَالَ السَّكِينَةُ الإيمَانُ.
3. A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from ibn Mahbub from al-‘Ala’ from Muhammad ibn Muslim from abu Ja’far عليه السلام who has said the following: “Abu Ja’far عليه السلام has said, ‘Serenity (al-Sakinah) is belief.”
