Then he got up to pray, so she took his clothes and said, "Won't you perform ablution, O Messenger of Allah?" He said, "What is the matter, O my little daughter?" She said," You have eaten from what the fire has touched." He said," Verily, the purest of your food is that which has been touched by the fire."  

أَنَّهُ دَخَلَ عَلَى رَسُولِ اللهِ ﷺ بَيْتَ فَاطِمَةَ فَنَاوَلَتْهُ كَتِفَ شَاةٍ مَطْبُوخَةٍ فَأَكَلَهَا ثُمَّ قَامَ يُصَلِّي فَأَخَذَتْ ثِيَابَهُ فَقَالَتْ أَلَا تَوَضَّأُ يَا رَسُولَ اللهِ؟ قَالَ «مِمَّ يَا بُنَيَّةُ؟» قَالَتْ قَدْ أَكَلْتَ مِمَّا مَسَّتْهُ النَّارُ قَالَ «إِنَّ أَطْهَرَ طَعَامِكُمْ لَمَا مَسَّتْهُ النَّارُ»
