"Should I perform Wudu' after eating food that I see in the Book of Allah is permissible because fire has touched it?" Abu Hurairah gathered some pebbles and said: "I bear witness (as many times as) the number of these pebbles, that the Messenger of Allah ﷺ said: 'Perform Wudu' from that which has been touched by fire.'"

لأَنَّ النَّارَ مَسَّتْهُ فَجَمَعَ أَبُو هُرَيْرَةَ حَصًى فَقَالَ أَشْهَدُ عَدَدَ هَذَا الْحَصَى أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ تَوَضَّئُوا مِمَّا مَسَّتِ النَّارُ
