Chapter: The Case of One Who Eats or Drinks but Has Doubts About Its Taking Place before or after Dawn 3ـ عَلِيُّ بْنُ إِبْرَاهِي٠َ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُ٠ُعَاوِيَةَ بْنِ عَ٠َّارٍ قَالَ قُلْتُ لأَبِي عَبْدِ الله (عَلَيْهِ السَّلاَ٠ُرُ الْجَارِيَةَ أَنْ تَنْظُرَ طَلَعَ الْفَجْرُ أَ٠ْ لا فَتَقُولُ لَ٠ْ يَطْلُعْ فَآكُلُ ثُ٠َّ أَنْظُرُهُ فَأَجِدُهُ قَدْ طَلَعَ حِينَ نَظَرَتْ قَالَ تُتِ٠َا إِنَّكَ لَوْ كُنْتَ أَنْتَ الَّذِي نَظَرْتَ ٠َا كَانَ عَلَيْكَ قَضَاؤُهُ.

He (the Imam) said, ‘You are required to complete that fast and make Qada’ (compensatory fast for it); however, if you yourself had looked first before eating there would have been no Qada’ (compensatory fast) upon you.’” حسن - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (16/263))
