That the Prophet ﷺ said: "What an excellent condiment vinegar is."  

عَنِ النَّبِيِّ ﷺ قَالَ نِعْمَ الإِدَامُ الْخَلُّ قَالَ وَفِي الْبَابِ عَنْ عَائِشَةَ وَأُمِّ هَانِئٍ  

That the Messenger of Allah ﷺ said: "What an excellent condiment vinegar is." Another chain with similar except that he ﷺ said: "What an excellent condiment, or, (the most excellent of) condiments is vinegar."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ نِعْمَ الإِدَامُ الْخَلُّ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الرَّحْمَنِ أَخْبَرَنَا يَحْيَى بْنُ حَسَّانَ عَنْ سُلَيْمَانَ بْنِ بِلاَلٍ بِهَذَا الإِسْنَادِ نَحْوَهُ إِلاَّ أَنَّهُ قَالَ نِعْمَ الإِدَامُ أَوِ الأُدْمُ الْخَلُّ  

"The Messenger of Allah ﷺ entered upon me and said: 'Do you have anything?' I said: 'No, except a piece of hard bread and vinegar.' so he said: 'Bring it, for a house that has vinegar is not impoverished of condiments."  

دَخَلَ عَلَىَّ رَسُولُ اللَّهِ ﷺ فَقَالَ هَلْ عِنْدَكُمْ شَيْءٌ فَقُلْتُ لاَ إِلاَّ كِسَرٌ يَابِسَةٌ وَخَلٌّ فَقَالَ النَّبِيُّ ﷺ قَرِّبِيهِ فَمَا أَقْفَرَ بَيْتٌ مِنْ أُدْمٍ فِيهِ خَلٌّ  

That the Prophet ﷺ said: "What an excellent condiment vinegar is." There are narrations on this topic from 'Aishah and Umm Hani', and this is more correct than the narration of Mubarak bin Sa'eed (no. 1839).  

عَنِ النَّبِيِّ ﷺ قَالَ نِعْمَ الإِدَامُ الْخَلُّ هَذَا أَصَحُّ مِنْ حَدِيثِ مُبَارَكِ بْنِ سَعِيدٍ
