Sunan Ibn Majah, Volume 4, Book 29, Hadith 3318 (DarusSalam) ⓘ
Umm Sa’d said: “The Messenger of Allah entered upon ‘Aishah, when I was with her, and said: ‘Is there any food?’ She said: ‘We have bread, dates and vinegar.’ The Messenger of Allah said: ‘What a blessed condiment vinegar is. O Allah, bless vinegar, for it was the condiment of the Prophets before me, and no house will ever be poor in which there is vinegar.’”
حَدَّثَنَا الْعَبَّاسُ بْنُ عُثْمَانَ الدِّمَشْقِيُّ، حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ، حَدَّثَنَا عَنْبَسَةُ بْنُ عَبْدِ الرَّحْمَنِ، عَنْ مُحَمَّدِ بْنِ زَاذَانَ، أَنَّهُ حَدَّثَهُ قَالَ حَدَّثَتْنِي أُمُّ سَعْدٍ، قَالَتْ دَخَلَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ عَلَى عَائِشَةَ وَأَنَا عِنْدَهَا فَقَالَ " هَلْ مِنْ غَدَاءٍ " . قَالَتْ عِنْدَنَا خُبْزٌ وَتَمْرٌ وَخَلٌّ . فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " نِعْمَ الإِدَامُ الْخَلُّ اللَّهُمَّ بَارِكْ فِي الْخَلِّ فَإِنَّهُ كَانَ إِدَامَ الأَنْبِيَاءِ قَبْلِي وَلَمْ يَفْتَقِرْ بَيْتٌ فِيهِ خَلٌّ " .
