What was narrated concerning one who breaks his fast out of forgetfulness
Sunan Ibn Majah
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَلِيُّ بْنُ مُحَمَّدٍ، قَالاَ حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ فَاطِمَةَ بِنْتِ الْمُنْذِرِ، عَنْ أَسْمَاءَ بِنْتِ أَبِي بَكْرٍ، قَالَتْ: أَفْطَرْنَا عَلَى عَهْدِ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ فِي يَوْمِ غَيْمٍ ثُمَّ طَلَعَتِ الشَّمْسُ . قُلْتُ لِهِشَامٍ: أُمِرُوا بِالْقَضَاءِ؟ قَالَ: لاَ بُدَّ مِنْ ذَلِكَ .
It was narrated that Asma’ bint Abu Bakr said: “We broke our fast on a cloudy day at the time of the Messenger of Allah (ﷺ), then the sun appeared.” I (one of the narrators) said to Hisham: "Were they commanded to make up for that day?" He said: "It had to be made up." (According to Hisham's opinion).
