Does evil come from Allah?

Evil does not come from Allah. Evils are not of existential things, as existence is pure goodness.

If someone, for instance, hit another one until he made him lose his ability to move, then this person has acquired the attribute of oppression, and oppression is evil.

However, the existence of power in the one who grabs a stick to hit someone else is not evil.

Moreover, the existence of the will that Allah granted him is not evil.

Also the existence of his ability to move his hand is not evil,

and the existence of hitting function in the stick is not evil.

All these existential things are good in themselves and do not acquire the attribute of evil unless they lead to harm by being misused, which is the harm of paralysis as in the previous example. Consequently, the existence of the scorpion and the serpent is not evil in itself unless man comes their way and gets bitten. Evil must not be attributed to Allah's acts, which are pure goodness; rather, it must be attributed to the events that Allah has allowed to occur according to His decree and has predestined for a certain wisdom that leads to many benefits, despite His ability to prevent its occurrence. Such events were the result of man's misuse of this goodness.
