Does the use of dried grapes (moyez) and raisins in food and frying them cause impurity and make the food unlawful? The religious ruling on this question has been answered by religious authorities.
Ruling on Cooking Raisins in Food
Most religious scholars have stated that dates, dried grapes (moyez), raisins, and their water remain pure even when they boil, and eating them is considered lawful. However, some scholars say: if dried grapes and raisins are added to food and boiled to the extent that water penetrates into them and the water inside also boils, it becomes unlawful to eat, though it is not impure, and they can be removed from the food and eaten. There is no issue with frying or steaming them in rice or similar dishes. Regarding dates, if their water enters the food, boils, and is consumed, it is permissible. However, if the amount is such that it boils but does not dissipate, it cannot be eaten.
