1ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ سُلَيْمٍ الْفَرَّاءِ عَمَّنْ حَدَّثَهُ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ إِذَا دَعَوْتَ فَظُنَّ أَنَّ حَاجَتَكَ بِالْبَابِ.
1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Sulaym al-Farra’ from those whom he has mentioned (in his book) from Abu ‘Abdillah (a.s.) who has said the following: “Abu ‘Abd Allah (a.s.) has said, ‘Whenever you pray and plead before Allah for help, consider that what you have asked for has arrived at the door.’”
