Book 5: Fasting
وَعَنْ أَبِي هُرَيْرَةَ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ مَنْ نَسِيَ وَهُوَ صَائِمٌ, فَأَكَلَ أَوْ شَرِبَ, فَلْيُتِمَّ صَوْمَهُ, فَإِنَّمَا أَطْعَمَهُ اَللَّهُ وَسَقَاهُ } مُتَّفَقٌ عَلَيْهِ 1‏ .‏
Abu Hurairah (RAA) narrated that The Messenger of Allah (ﷺ) said:

‘Whoever forgets that he is fasting, and eats or drinks is to complete his fast, as it was Allah who fed him and gave him something to drink." Agreed upon.
