كَيْفَ يَهْدِي اللَّهُ قَوْمًا كَفَرُوا بَعْدَ إِيمَانِهِمْ وَشَهِدُوا أَنَّ الرَّسُولَ حَقٌّ وَجَاءَهُمُ الْبَيِّنَاتُ ۚ وَاللَّهُ لَا يَهْدِي الْقَوْمَ الظَّالِمِينَ
How would God guide a people who have disbelieved after their belief, and after they have borne witness that the Messenger is true and after the clear proofs (of his Messengership and the Divine origin of the Book he has brought) have come to them? God guides not wrongdoing people. (Al ‘Imrān 3:86)
Those who advocate evil, impropriety, and infidelity and support evil-doers and unbelievers even though they witnessed good and truth in all their beauty and evil and falsehood in all their ugliness are arrogant, inhumane people who live lives of deviation. They are the unfortunate ones who have corrupted their nature or dispositions and blunted their ability to follow right guidance so much that, in accordance with the Divine Practice or way of dealing with His creation, God no longer guides them to the Straight Path. Since those people have left the sacred gravitation of Islam, becoming more and more distant from it, they will always be inclined to distancing themselves from Islam, constantly accusing and disparaging the center they have left, and they will therefore darken their nature in excessive degrees. In this way, they will expose the believers in a negative way as if they knew them well and boost the morale of the adherents of unbelief and make them happy while they overwhelm the believers with sorrow and refraction.
In addition, since they left Islam, which is like the sun in respect to its light, compared to other religions that resemble a candle, those ill-natured people will always be searching. However, unable to find what they are searching for, their life will come to an end in the search of something im-possible to be found. In the process, they set a bad example for the naïve, bewildered masses.
