O you who have believed, do not follow the footsteps of Satan. And whoever follows the footsteps of Satan - indeed, he enjoins immorality and wrongdoing. And if not for the favor of Allah upon you and His mercy, not one of you would have been pure, ever, but Allah purifies whom He wills, and Allah is Hearing and Knowing.

Tafsir of Verse 21
O believers, follow not the steps of Satan; for whosoever follows the steps of Satan, assuredly he bids to indecency and dishonour. But for God's bounty to you and His mercy not one of you would have been pure ever; but God purifies whom He will; and God is All-hearing, All-knowing.
O ye who believe! follow not Satan's footsteps: if any will follow the footsteps of Satan, he will (but) command what is shameful and wrong: and were it not for the grace and mercy of Allah on you, not one of you would ever have been pure: but Allah doth purify whom He pleases: and Allah is One Who hears and knows (all things).
