[Machine] Ibn Masud said, "Whoever breaks their fast for one day in Ramadan without a valid excuse will meet Allah with that sin, even if they were to fast the entire year. If Allah wills, He may forgive them, and if He wills, He may punish them."
ابْنُ مَسْعُودٍ «مَنْ أَفْطَرَ يَوْمًا مِنْ رَمَضَانَ مِنْ غَيْرِ رُخْصَةٍ لَقِيَ اللهَ بِهِ وَإِنْ صَامَ الدَّهْرَ كُلَّهُ إِنْ شَاءَ غَفَرَ لَهُ وَإِنْ شَاءَ عَذَّبَهُ»
[Machine] Whoever breaks (fast) one day of Ramadan without justification, their fasting for the rest of their life will not be accepted until they meet Allah. If He wishes, He will forgive them, and if He wishes, He will punish them. Another narration from Ibn Mas'ood mentions (the same).
مَنْ أَفْطَرَ يَوْمًا مِنْ رَمَضَانَ مِنْ غَيْرِ عِلَّةٍ لَمْ يُجْزِهِ صِيَامُ الدَّهْرِ حَتَّى يَلْقَى اللهَ ﷻ فَإِنْ شَاءَ غَفَرَ لَهُ وَإِنْ شَاءَ عَذَّبَهُ وَرُوِيَ مِنْ وَجْهٍ آخَرَ عَنِ ابْنِ مَسْعُودٍ
