'Abdullah b. Ibrahim b. Qariz reported that he found Abu Huraira performing ablution in the mosque, who said: I am performing ablution because of having eaten pieces of cheese, for I heard the Messenger of Allah (ﷺ) say: Perform ablution (after eating anything) touched by fire.

قَالَ ابْنُ شِهَابٍ أَخْبَرَنِي عُمَرُ بْنُ عَبْدِ الْعَزِيزِ، أَنَّ عَبْدَ اللَّهِ بْنَ إِبْرَاهِيمَ بْنِ قَارِظٍ، أَخْبَرَهُ أَنَّهُ، وَجَدَ أَبَا هُرَيْرَةَ يَتَوَضَّأُ عَلَى الْمَسْجِدِ فَقَالَ إِنَّمَا أَتَوَضَّأُ مِنْ أَثْوَارِ أَقِطٍ أَكَلْتُهَا لأَنِّي سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏ "‏ تَوَضَّئُوا مِمَّا مَسَّتِ النَّارُ ‏"‏ ‏.‏
