The Prophet ﷺ said: If anyone breaks his fast one day in Ramadan without a concession granted to him by Allah, a perpetual fast will not atone for it.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ أَفْطَرَ يَوْمًا مِنْ رَمَضَانَ مِنْ غَيْرِ رُخْصَةٍ رَخَّصَهَا اللَّهُ لَهُ لَمْ يَقْضِ عَنْهُ صِيَامُ الدَّهْرِ  

Sufyan and Shu'bah differed among themselves on the name of the narrator Ibn al-Mutawwas and Abu al-Mutawwas.  

قَالَ النَّبِيُّ ﷺ مِثْلَ حَدِيثِ ابْنِ كَثِيرٍ وَسُلَيْمَانَ
