During the last centuries, great religious traditions as well as prominent philosophical and theological schools have been facing the so-called "problem of evil" and trying to solve it in a reasonable and convincing way. This paper seeks to explore Muslim philosophers' approach to the problem and examine their proposed solutions for it. After the main versions of the problem in Islamic philosophy are briefly sketched, the author explains its view about the non-existential nature of evil. At this stage, he discusses the challenge of "apprehensional evil" and three reactions to it. Then he turns to three main solutions proposed by Muslim philosophers in order to meet three versions of the problem of evil, i.e., the problem of evils and God's decree, the problem of creation-dualism and the problem of evils and Divine wisdom.
