Translation:

6. Verily Satan is an enemy to you: so treat him as an enemy. He only invites his adherents that they may become Companions of the Blazing Fire.

Notes (Tafseer)

3878. Evil is our enemy and should be treated as such. It is really foreign to our nature, however much it may disguise itself to deceive us as our friend, or a part of our own nature. Personifying the Spirit of Evil, we may say that he wants us to share in his own damnation. Shall we allow ourselves to fall into his snare?
