Notes (Tafseer)

1976. To be sincere in the worship of Allah is to obtain purification from all stain of evil and exemption from all influence of evil. It changes the whole nature of man. After that, evil cannot touch him. Evil will acknowledge him to be beyond its power and will not even tempt him. Apart from such purified souls, everyone who worships Allah invites Allah's grace to protect him. But if he puts himself in the way of wrong and deliberately chooses evil, he must take the consequences. The blame is not even on Satan, the power of evil, it is on the sinner himself, who puts himself into his power; xiv. 22: xv. 42.
