5ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حُسَيْنٍ الأحْمَسِيِّ عَنْ رَجُلٍ عَنْ أَبِي جَعْفَرٍ (عَلَيهِ السَّلام) قَالَ لا وَالله لا يُلِحُّ عَبْدٌ عَلَى الله عَزَّ وَجَلَّ إِلا اسْتَجَابَ الله لَهُ.
5. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Husayn al-Ahmasi from a man from abu Ja’far (a.s.) who has said the following: “Abu Ja’far (a.s.) has said, ‘By Allah, if a man insists before Allah, the Most Majestic, the Most Holy, on praying and pleading for help. He will accept his prayers.’”
