"Whoever eats or drinks forgetfully, then he has not broken (the fast), for it was only a provision that Allah provided for him."  

الترمذي:٧٢١حَدَّثَنَا أَبُو سَعِيدٍ الأَشَجُّ حَدَّثَنَا أَبُو خَالِدٍ الأَحْمَرُ عَنْ حَجَّاجِ بْنِ أَرْطَاةَ عَنْ قَتَادَةَ عَنِ ابْنِ سِيرِينَ عَنْ أَبِي هُرَيْرَةَ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ أَكَلَ أَوْ شَرِبَ نَاسِيًا فَلاَ يُفْطِرْ فَإِنَّمَا هُوَ رِزْقٌ رَزَقَهُ اللَّهُ
