وَقْتُ سُقُوطِ الْقُرْصِ وَ وُجُوبِ الْإِفْطَارِ مِنَ الصِّيَامِ أَنْ يَقُومَ بِحِذَاءِ الْقِبْلَةِ وَ يَتَفَقَّدَ الْحُمْرَةَ الَّتِي تَرْتَفِعُ مِنَ الْمَشْرِقِ فَإِذَا جَازَتْ قِمَّةَ الرَّأْسِ إِلَى نَاحِيَةِ الْمَغْرِبِ فَقَدْ وَجَبَ الْإِفْطَارُ وَ سَقَطَ الْقُرْصُ .
Translation
A number of our companions, from Sahl Bin Ziyad, from Muhammad Bin Isa Bin Ubeyd, from Ibn Abu Umeyr, from the one who mentioned it, (It has been narrated) from Abu Abdullah<sup>asws</sup> having said: ‘The time of the fall of the disc (sun) and the Obligation of breaking from the Fasts is that, one stands facing the Qiblah and inspects the redness which rises from the east. So when it passes overhead towards the direction of the west, so the breaking of the Fast is Obligated, and the disc falls (sun sets)’.
