Ṣāliḥ Āli-Shaykh discusses the principle that "the ends justify the means" and argues that it is incorrect from an Islamic perspective. The means, or methods, used must be permissible in and of themselves according to Islamic law, not just the intended outcome. For example, political demonstrations are not allowed as a means of pressuring leaders for change, even if the goal is sincere, because demonstrations are forbidden. The permissible means must be used to achieve permissible ends - one cannot use forbidden means and justify it based on desiring a good end result. The means and ends both require independent evaluation according to Islamic rulings.
