3ـ أَبُو عَلِيٍّ الأشْعَرِيُّ عَنْ مُحَمَّدِ بْنِ عَبْدِ الْجَبَّارِ عَنْ صَفْوَانَ عَنْ بِسْطَامَ الزَّيَّاتِ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ إِنَّ الدُّعَاءَ يَرُدُّ الْقَضَاءَ وَقَدْ نَزَلَ مِنَ السَّمَاءِ وَقَدْ أُبْرِمَ إِبْرَاماً.
3. Abu Ali al-Ash’ari has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan from Bistam al-Zayyat from Abu ‘Abdillah (a.s.) who has said the following: “Abu ‘Abd Allah (a.s.) has said, ‘Prayer and pleading before Allah for help, repeals al- Qada ’, what is already determined, has already come down from heavens and is firmly established.’”
