Consumption of Food that Containing Red Wine Vinegar

In responding to this, we would like to cite Dr. `Abdul-Fattah Idrees , a professor of comparative jurisprudence who said:

Muslim Jurists have unanimously agreed that if the wine changes by itself, that is without any human intervention, to be a vinegar, this vinegar becomes pure and permissible to be consumed.

However, if the change is due to human intervention, such as through adding chemicals or the like means, the jurists differed over the permissibility of consuming it. The most preponderant opinion is that this kind of vinegar is still impure and impermissible for Muslims.”
