3ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ الْبَرْقِيِّ عَنِ الْقَاسِمِ بْنِ يَحْيَى عَنْ جَدِّهِ الْحَسَنِ بْنِ رَاشِدٍ عَنْ أَبِي الْحَسَنِ مُوسَى بْنِ جَعْفَرٍ (عَلَيْهما السَّلام) قَالَ سُئِلَ عَنْ مَعْنَى الله فَقَالَ اسْتَوْلَى عَلَى مَا دَقَّ وَجَلَّ.
3. A group of our people has narrated from Ahmad ibn Muhammad from al-Barqi from al-Qasim ibn Yahya from his grandfather al-Hassan ibn Rashid from abul Hassan Musa ibn Ja‘far , who was questioned about the meaning of the word Allah. The Imam replied, “He (Allah) dominates all things small or big.”
