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.
أَخْبَرَهُ أَنَّهُ وَجَدَ أَبَا هُرَيْرَةَ يَتَوَضَّأُ عَلَى الْمَسْجِدِ فَقَالَ إِنَّمَا أَتَوَضَّأُ مِنْ أَثْوَارِ أَقِطٍ أَكَلْتُهَا لأَنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ تَوَضَّئُوا مِمَّا مَسَّتِ النَّارُ
"I saw Abu Hurairah performing Wudu' on the roof of the Masjid ans he said: 'I ate some tough cheese, so I performed Wudu' because of that. I heard the Messenger of Allah ﷺ commanding us to do Wudu' from that which has been touched by fire.'"
رَأَيْتُ أَبَا هُرَيْرَةَ يَتَوَضَّأُ عَلَى ظَهْرِ الْمَسْجِدِ فَقَالَ أَكَلْتُ أَثْوَارَ أَقِطٍ فَتَوَضَّأْتُ مِنْهَا إِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَأْمُرُ بِالْوُضُوءِ مِمَّا مَسَّتِ النَّارُ
"Perform Wudu' from that which has been heated with fire." (Using translation from Nasāʾī 178)
أَنَّ النَّبِيَّ ﷺ قَالَ تَوَضَّئُوا مِمَّا مَسَّتِ النَّارُ
[Machine] "Do you know what I am performing ablution with? It is from the leaves of a plant called aqit, which I have consumed. Verily, I heard the Messenger of Allah ﷺ saying, 'Perform ablution with the water that has been touched by fire.'"
أَتَدْرِي مِمَّا أَتَوَضَّأُ؟ مِنْ أَثْوَارِ أَقِطٍ أَكَلْتُهَا إِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ تَوَضَّئُوا مِمَّا مَسَّتِ النَّارُ
[Machine] He informed him that he found Abu Hurairah performing ablution at the back of the mosque. Abu Hurairah said, "I am performing ablution with the remnants of a sheep that I had eaten because the Messenger of Allah ﷺ said, 'Perform ablution with what the fire has touched.'"
أَخْبَرَهُ أَنَّهُ وَجَدَ أَبَا هُرَيْرَةَ يَتَوَضَّأُ عَلَى ظَهْرِ الْمَسْجِدِ فَقَالَ أَبُو هُرَيْرَةَ إِنَّمَا أَتَوَضَّأُ مِنْ أَثْوَارِ أَقِطٍ أَكَلْتُهَا لِأَنَّ رَسُولَ اللهِ ﷺ قَالَ تَوَضَّئُوا مِمَّا مَسَّتِ النَّارُ
"The Messenger of Allah said: 'Perform ablution after (eating) that which has been changed by fire.'" (Using translation from Ibn Mājah 486)
قَالَ رَسُولُ اللهِ ﷺ تَوَضَّئُوا مِمَّا مَسَّتِ النَّارُ وَلَوْ مِنْ تَوْرِ أَقِطٍ
[Machine] Abu Hurayrah ate a rib of a sheep, then he performed ablution (wudu). Afterwards, he said, "Do you know why I performed ablution? I ate a rib of a sheep. I heard the Messenger of Allah ﷺ say, 'Perform ablution from whatever has touched the fire.'"
أَنَّ أَبَا هُرَيْرَةَ أَكَلَ أَثْوَارَ أَقِطٍ فَتَوَضَّأَ ثُمَّ قَالَ أَتَدْرُونَ لِمَ تَوَضَّأْتُ؟ إِنِّي أَكَلْتُ أَثْوَارَ أَقِطٍ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «تَوَضَّأْ مِمَّا مَسَّتِ النَّارُ»
[Machine] "He found Abu Hurayrah on the back of the mosque performing ablution, so he asked him. Abu Hurayrah said, 'I am performing ablution from the leftovers of a cat I ate. Indeed, the Prophet ﷺ said, 'Perform ablution from what the fire has touched.'"
أَنَّهُ وَجَدَ أَبَا هُرَيْرَةَ عَلَى ظَهْرِ الْمَسْجِدِ يَتَوَضَّأُ فَسَأَلَهُ قَالَ أَبُو هُرَيْرَةَ إِنَّمَا أَتَوَضَّأُ مِنْ أَثْوَارِ أَقِطٍ أَكَلْتُهَا إِنَّ النَّبِيَّ ﷺ قَالَ «تَوَضَّأْ مِمَّا مَسَّتْهُ النَّارُ»
