Shaytan works by exploiting our own weaknesses and attachments. If we have trouble with tawakul (reliance on God), he will exploit our lack of firm footing, to make us constantly hesitant and afraid of the unknown. He will bombard us with irrational fears. He uses our chains against us. But we create those chains, thru our need for control. The greatest shield against shaytan is tawakul. It gives him nothing to chain us with. Tawakul frees us from ourselves and the bondage of fear. The bondage of shaytan.
