If after getting healed from an illness an organ of the body permanently shivers, then give such a person the fried brain of a rabbit to eat. This would be extremely beneficial. If someone keeps on eating the brain of a rabbit, he/she does not develop signs of aging quickly. If the brain of the rabbit is fried and eaten with black pepper, it is quite beneficial for flue. (Hayaat-ul-haiwaan) (Muhammad Saeed Alwi, Chakwaal)
