The Messenger of Allah ﷺ said: “When the night comes from here and the day departs from here, it is time for the fasting person to break his fast,” meaning the east and the west,
قَالَ رَسُولُ اللهِ ﷺ إِذَا أَقْبَلَ اللَّيْلُ وَقَالَ مَرَّةً جَاءَ اللَّيْلُ مِنْ هَاهُنَا وَذَهَبَ النَّهَارُ مِنْ هاَهُنَا فَقَدْ أَفْطَرَ الصَّائِمُ يَعْنِي الْمَشْرِقَ وَالْمَغْرِبَ
