“The Messenger of Allah (ﷺ) 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 (ﷺ) 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.’”
Sunan Ibn Majah Book 29, Hadith 68
