Sunan Ibn Majah 3318

Umm Sa’d said:“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.’”
