What is the ruling on lamb wrestling in Algeria, Morocco, and Tunisia, and what is the ruling on the money earned from it, betting on it, and thousands of people watching it?

Ram fighting is a form of incitement (tahreesh) that is forbidden by Islamic law. There are prohibitions against inciting animals against each other. The reason for this prohibition is that it causes pain and exhaustion to the animals without any benefit; rather, it is mere amusement. The Islamic Fiqh Council has issued a fatwa declaring such fighting forbidden, and any financial wagering resulting from it is considered unlawful money.
