The best of condiments or condiment is vinegar.  

أَنَّ النَّبِيَّ ﷺ قَالَ نِعْمَ الأُدُمُ أَوِ الإِدَامُ الْخَلُّ  

" The best condiment." And he did not doubt (about this word).  

وَقَالَ نِعْمَ الأُدُمُ وَلَمْ يَشُكَّ  

We have nothing with us but vinegar. He asked for it, he began to eat it, and then said: Vinegar is a good condiment, vinegar is a good condiment.  

أَنَّ النَّبِيَّ ﷺ سَأَلَ أَهْلَهُ الأُدُمَ فَقَالُوا مَا عِنْدَنَا إِلاَّ خَلٌّ فَدَعَا بِهِ فَجَعَلَ يَأْكُلُ بِهِ وَيَقُولُ نِعْمَ الأُدُمُ الْخَلُّ نِعْمَ الأُدُمُ الْخَلُّ  

Messenger of Allah ﷺ took hold of my hand one day (and led me) to his residence. There was presented to him some pieces of bread, whereupon he said: Is there no condiment? They (the members of his household) said: No, except some vinegar. He (the Holy Prophet) said: Vinegar is a good condiment. Jabir said: I have always loved vinegar since I heard it trom Allah's Apostle ﷺ. Talha said: I have always loved vinegar since I heard about it from Jabir.  

أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ يَقُولُ أَخَذَ رَسُولُ اللَّهِ ﷺ بِيَدِي ذَاتَ يَوْمٍ إِلَى مَنْزِلِهِ فَأَخْرَجَ إِلَيْهِ فِلَقًا مِنْ خُبْزٍ فَقَالَ مَا مِنْ أُدُمٍ فَقَالُوا لاَ إِلاَّ شَىْءٌ مِنْ خَلٍّ قَالَ فَإِنَّ الْخَلَّ نِعْمَ الأُدُمُ قَالَ جَابِرٌ فَمَا زِلْتُ أُحِبُّ الْخَلَّ مُنْذُ سَمِعْتُهَا مِنْ نَبِيِّ اللَّهِ ﷺ وَقَالَ طَلْحَةُ مَا زِلْتُ أُحِبُّ الْخَلَّ مُنْذُ سَمِعْتُهَا مِنْ جَابِرٍ  

" Vinegar is a good condiment." But in the hadith transmitted through this chain of transmitters, there is no mention of the subsequent part.  

أَنَّ رَسُولَ اللَّهِ ﷺ أَخَذَ بِيَدِهِ إِلَى مَنْزِلِهِ بِمِثْلِ حَدِيثِ ابْنِ عُلَيَّةَ إِلَى قَوْلِهِ فَنِعْمَ الأُدُمُ الْخَلُّ وَلَمْ يَذْكُرْ مَا بَعْدَهُ  

While I was sitting in my house there happened to pass by me Messenger of Allah ﷺ. He made a gesture to me and I stood up for him. He took hold of my hand until we came to one of the apartments of his wives. He entered and then asked me to get in. So I entered and there was hanging a curtain beside her. He (the Holy Prophet) said: Is there any food (with you)? They (the members of the household) said: Yes And then there were brought three loaves of bread for him (the Holy Prophet) and placed in the basket of palm leaves. Messenger of Allah ﷺ picked up one loaf and placed that before him, and then picked up another one and placed it before me. He then picked up the third one and broke it into two parts, and kept the one-half before him and the other half before me, and then said: Is there any condiment? They (the members of the household) said: There is nothing (in the form of condiment) but some vinegar only. He said: Bring that, for vinegar is a good condiment.  

كُنْتُ جَالِسًا فِي دَارِي فَمَرَّ بِي رَسُولُ اللَّهِ ﷺ فَأَشَارَ إِلَىَّ فَقُمْتُ إِلَيْهِ فَأَخَذَ بِيَدِي فَانْطَلَقْنَا حَتَّى أَتَى بَعْضَ حُجَرِ نِسَائِهِ فَدَخَلَ ثُمَّ أَذِنَ لِي فَدَخَلْتُ الْحِجَابَ عَلَيْهَا فَقَالَ هَلْ مِنْ غَدَاءٍ فَقَالُوا نَعَمْ فَأُتِيَ بِثَلاَثَةِ أَقْرِصَةٍ فَوُضِعْنَ عَلَى نَبِيٍّ فَأَخَذَ رَسُولُ اللَّهِ ﷺ قُرْصًا فَوَضَعَهُ بَيْنَ يَدَيْهِ وَأَخَذَ قُرْصًا آخَرَ فَوَضَعَهُ بَيْنَ يَدَىَّ ثُمَّ أَخَذَ الثَّالِثَ فَكَسَرَهُ بِاثْنَيْنِ فَجَعَلَ نِصْفَهُ بَيْنَ يَدَيْهِ وَنِصْفَهُ بَيْنَ يَدَىَّ ثُمَّ قَالَ هَلْ مِنْ أُدُمٍ قَالُوا لاَ إِلاَّ شَىْءٌ مِنْ خَلٍّ قَالَ هَاتُوهُ فَنِعْمَ الأُدُمُ هُوَ
