Arabic (Original)
حَدَّثَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ وَهُوَ ابْنُ عُلَيَّةَ عَنْ هِشَامِ بْنِ حَسَّانَ وَيَزِيدُ بْنُ هَارُونَ قَالَ أَخْبَرَنَا هِشَامٌ عَنِ ابْنِ سِيرِينَ عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ نَسِيَ وَهُوَ صَائِمٌ فَأَكَلَ أَوْ شَرِبَ فَلْيُتِمَّ صَوْمَهُ فَإِنَّمَا أَطْعَمَهُ اللَّهُ وَسَقَاهُ.

Isma'il ibn Ibrahim, who is Ibn Ulayyah, narrated to us, from Hisham ibn Hassan - and Yazid ibn Harun said: Hisham informed us - from Ibn Sirin, from Abu Hurayrah who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever forgets while fasting and eats or drinks, let him complete his fast, for it was Allah who fed him and gave him drink."
