wine vinegar: Is it permissable

[Muslimah]

Assalamu alayka Sheikh: I would like to know why the scholars are stating that the wine vinegar is permissible when the Messenger of Allah (may Allah send prayers and peace on him) and the companions, such as Umar bin Khattab, have forbidden vinegar made from wine?

I did some more research on this and I found http://islamqa.info/en/ref/2283 Ruling on vinegar made from wine. These are the hadiths from the Messenger of Allah (may Allah send prayers and peace on him).

Jaabir (may Allaah be pleased with him) reported that the Prophet (peace and blessings of Allaah be upon him) said: “What a good food is vinegar.” (Reported by Muslim, 3/1623)

Abu Talhah (may Allaah be pleased with him) reported that the Prophet (peace and blessings of Allaah be upon him) was asked about some orphans who had inherited some wine. He said, “Pour it away.” He was asked, “Could they not make it into vinegar?” He said, “No.” (Reported by Muslim).

Anas ibn Maalik (may Allaah be pleased with him) who said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) was asked whether wine could be changed to be used as vinegar. He said, ‘No.’” (Reported by Muslim).

‘Umar (may Allaah be pleased with him) said: “… There is nothing wrong with a man buying vinegar from the people of the Book, if they sell it, so long as he knows that they did not deliberately process it from wine.” (Al-Mughni, 8/330)
