٢ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنِ ابْنِ أُذَيْنَةَ عَنْ زُرَارَةَ وَبُكَيْرٍ ابْنَيْ أَعْيَنَ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ الْسَّلام) قَالَ إِذَا اسْتَيْقَنَ أَنَّهُ زَادَ فِي صَلاَتِهِ الْمَكْتُوبَةِ لَمْ يَعْتَدَّ بِهَا وَاسْتَقْبَلَ صَلاَتَهُ اسْتِقْبَالاً إِذَا كَانَ قَدِ اسْتَيْقَنَ يَقِيناً.
2. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ibn ’Udhaynah from Zurarah and ibn Bukayr ibn A’yan who has said the following: “Abu Ja‘far , has said, ‘If one of you is certain that he has increased something in his obligatory Salah (prayer) he does not depend on it and performs his Salah (prayer) again if he is certain of such increase.’”
