'Aayeshah Radiyallahu 'Anha says: "Rasulullah Sallallahu 'Alayhi Wasallam once said: 'What a nice curry vinegar is'".
The reason being there is not much trouble in it. Bread can easily be eaten with it. It is always easily available. It also keeps away formalities. Besides one lives in this world for a little while. Vinegar has many benefits in it. It is an antidote for poison. It stops phlegm and gall. It helps digest food, kills the worms of the stomach and creates a good appetite. Due to its cold effect, it may not be good for some people. But it surely is a good curry which is obtained easily. In whatever way it is praised, its full benefits cannot be emphasised. It is stated in a hadith that Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam ate it and said: 'What a wonderful curry it is'. In another hadith it is stated that Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam made du'aa for barakah in it and said: "It was the curry of the previous Ambiyaa also'. In one hadith it is stated, 'The house that has vinegar in it, will not be in need' i.e. That house will not be in need of curry. These narrations have been mentioned in the Jam 'ule Wasaa-il from Ibn Maajah.
