Narrated Umm Habibah:

AbuSufyan ibn Sa'id ibn al-Mughirah reported that he entered upon Umm Habibah who presented him a glass of sawiq (a drink prepared with flour and water) to drink. He called for water and rinsed his mouth. She said: O my cousin, don't you perform ablution? The Prophet ﷺ said: Perform ablution after eating anything cooked with fire, or he said: anything touched by fire.

Abu Dawud said: The version of al-Zuhri has: O my paternal cousin.

حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا أَبَانُ، عَنْ يَحْيَى، - يَعْنِي ابْنَ أَبِي كَثِيرٍ - عَنْ أَبِي سَلَمَةَ، أَنَّ أَبَا سُفْيَانَ بْنَ سَعِيدِ بْنِ الْمُغِيرَةِ، حَدَّثَهُ أَنَّهُ، دَخَلَ عَلَى أُمِّ حَبِيبَةَ فَسَقَتْهُ قَدَحًا مِنْ سَوِيقٍ فَدَعَا بِمَاءٍ فَتَمَضْمَضَ فَقَالَتْ يَا ابْنَ أُخْتِي أَلاَ تَوَضَّأُ إِنَّ النَّبِيَّ ﷺ قَالَ
" تَوَضَّئُوا مِمَّا غَيَّرَتِ النَّارُ " . أَوْ قَالَ مِمَّا مَسَّتِ النَّارُ . قَالَ أَبُو دَاوُدَ فِي حَدِيثِ الزُّهْرِيِّ يَا ابْنَ أَخِي .
