Narrated Umm Hani' bint Abi Talib:

"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."

[Abu 'Eisa said:] This Hadith is Hasan Gharib from this route. We do not know of it as a Hadith of Umm Hani' except through this route. Abu Hamzah Ath-Thumali's (a narrator in the chain) name is Thabit bin Abi Safiyyah. And Umm Hani' died some time after 'Ali bin Abi Talib. I asked Muhammad about this Hadith. He said: "I do not know Ash-Sha'bi hearing from Umm Hani'." So I said: "How is Abu Hamzah according to you?" He said: "Ahmad bin Hanbal criticized him, but he is Muqarib (average) in Hadith to me."
