What was narrated concerning one who breaks his fast out of forgetfulness

It was narrated from Abu Hurairah that the Messenger of Allah (ﷺ) said:

"Whoever eats out of forgetfulness while fasting, let him complete his fast, for it is Allah Who has fed him and given him to drink."

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ عَوْفٍ، عَنْ خِلاَسٍ، وَمُحَمَّدِ بْنِ سِيرِينَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ: قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏

‏ مَنْ أَكَلَ نَاسِيًا وَهُوَ صَائِمٌ فَلْيُتِمَّ صَوْمَهُ فَإِنَّمَا أَطْعَمَهُ اللَّهُ وَسَقَاهُ ‏

‏ ‏.‏

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).

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 ‏.‏
