Answered by Shaykh Yūsuf Badāt
Is it permissible to eat Kosher meat? Are there any conditions?
Jazāk Allāh Khayr / Thank you for your question.
It is permissible to eat Kosher meat. The only condition is that the meat should genuinely be Kosher and not mixed with any non ḥalāl ingredients, such as wine.
Similar is the ruling of non-meat Kosher certified products. Usually most Kosher products also meet all the guidelines of ḥalāl. However, there are a few ingredients that may be Kosher which are non- ḥalāl, such as wine and gelatine. The muslim, ḥalāl-cautious consumer must verify Kosher certified products to have met Islamic guidelines.
