You may ask what is wrong with living under the rein of Satan and Taghut and following their commandments. This is one of the points addressed in the verses. The Glorious Qur'an gives us some answers in this regard. The first answer is that if you accept the Wilayat of Satan, he will gain control over all your constructive, creative and useful powers. Once you willingly accept the subjugation of Satan and Taghut, then you will never be able to get rid of it.
It does not matter what productive and creative capabilities you have, Taghut and Satan will take over you; and once he is in control, he will drag you to wherever he wants to. It is obvious that Satan and Taghut will not guide a man towards light, cognizance, goodness and spiritual existence; these are not his objectives. In fact, the primary goal of Satan and Taghut is his personal interests and he wants to achieve them; so he uses you for that purpose.
If you think about these few sentences, you will notice a hidden message that is verified by the historical facts. حلقه ای در گردنم افکنده دوست می کشد هر جا که خاطر خواه اوست This friend has put a leash on my neck and drags me wherever he pleases. The following verse of Chapter Nisa deserves our utmost attention and pondering.
