2ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ جَمِيلِ بْنِ دَرَّاجٍ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ قُلْتُ لَهُ إِنَّهُ يَقَعُ فِي قَلْبِي أَمْرٌ عَظِيمٌ فَقَالَ قُلْ لا إِلَهَ إِلا الله قَالَ جَمِيلٌ فَكُلَّمَا وَقَعَ فِي قَلْبِي شَيْ‏ءٌ قُلْتُ لا إِلَهَ إِلا الله فَيَذْهَبُ عَنِّي.

2. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Jamil ibn Darraj who has said the following: “Once I asked Abu ‘Abdillah (a.s.) ‘A great thing happens in my heart.’ The Imam told me to say, ‘No one deserves to be worshipped except Allah.’ Jamil has said, ‘Whenever anything happens in my heart I say, ‘No one deserves to be worshipped except Allah,’ and it goes away.’”
