Divine commandments;+How to avoid evil?

Show forgiveness, enjoin what is good, and turn away from the foolish (i.e. don't punish them).

And if an evil whisper comes to you from Shaitân (Satan) then seek refuge with Allâh. Verily, He is All-Hearer, All-Knower.

Surely when the God-fearing are touched by any instigation from Satan, they become conscious (of Allah), and at once they discern (the reality).

Al a'raaf 199-201
