Chapter: The Time of Breaking Fast after Sunset ِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ ٠َّدِ بْنِ عِيسَى بْنِ عُبَيْدٍ عَنِ ابْنِ أَبِي عُ٠َّنْ ذَكَرَهُ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَ٠) قَالَ وَقْتُ سُقُوطِ الْقُرْصِ وَوُجُوبِ الإِفْطَارِ ٠َ بِحِذَاءِ الْقِبْلَةِ وَيَتَفَقَّدَ الْحُ٠ْرَةَ الَّتِي تَرْتَفِعُ ٠َشْرِقِ فَإِذَا جَازَتْ قِ٠َّةَ الرَّأْسِ إِلَى نَاحِيَةِ الْ٠َغْرِبِ فَقَدْ وَجَبَ الإِفْطَارُ وَسَقَطَ الْقُرْصُ.

When it (redness) passes overhead toward the west, breaking fast becomes obligatory and the disk has fallen (it is sunset).’” شهور - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (16/270))
