"Perform Wudu' O son of my sister! For the Messenger of Allah ﷺ said: 'Perform Wudu' from that which has been touched by fire.'" (Using translation from Nasāʾī 180)
أَنَّهُ دَخَلَ عَلَى أُمِّ حَبِيبَةَ فَسَقَتْهُ سَوِيقًا ثُمَّ قَامَ يُصَلِّي فَقَالَتْ لَهُ تَوَضَّأْ يَا ابْنَ أَخِي فَإِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ تَوَضَّئُوا مِمَّا مَسَّتِ النَّارُ
