Is eating sheep’s testicles permissible in Islam or not. Please explain to me in detail because some of my friends are eating them regularly; when I stopped them, they told me that they are permissible in Islam.

The edibles which are prohibited in Islam are clearly mentioned in the Qur’ān; sheep’s testicles are not among them. Therefore, they can be eaten. However, it is certainly not imperative to eat them; if you feel an aversion to a certain type of food you can refrain from it but you can’t stop others from eating food items that are not forbidden; do keep in mind that people have varied tastes regarding food; what may seem unpleasant to you might seem very delicious to others.
