The evil in Quran

The problem of evil at first seems to belie divine wisdom and what was said concerning the purposiveness of god,s actions and the fact that god means to benefit his creatures rather than deriving any benefit for himself. The evils that occur in the world are detrimental and harmful to all creatures and especially humankind.
On the one hand we know based on definitive rational reasoning that god,s actions are purposive and that the ends of his actions are to the benefit of the creatures. On the other hand however we cannot deny the existence of such evils that inflict pain and death on thousands of people and innumerous numbers of other creatures every year.
