﴿ أَفَمَن زُيِّنَ لَهُۥ سُوٓءُ عَمَلِهِۦ فَرَءَاهُ حَسَنًۭا ۖ فَإِنَّ ٱللَّهَ يُضِلُّ مَن يَشَآءُ وَيَهْدِى مَن يَشَآءُ ۖ فَلَا تَذْهَبْ نَفْسُكَ عَلَيْهِمْ حَسَرَٰتٍ ۚ إِنَّ ٱللَّهَ عَلِيمٌۢ بِمَا يَصْنَعُونَ ﴾

“Is, then, he to whom the evil of his own doings is [so] alluring that [in the end] he regards it as good [anything but a follower of Satan]? For, verily, God lets go astray him that wills [to go astray], just as He guides him that wills [to be guided]. Hence, [O believer,] do not waste thyself in sorrowing over them: verily, God has full knowledge of all that they do!”

Almighty God has blessed every man with the capability to think and distinguish between truth and untruth. One who utilizes this innate talent, receives proper guidance and one who does not is left to go astray. When Truth appears before a man, he has two options before him. If he accepts the Truth, his mind starts off in the right direction and he becomes a wayfarer journeying towards the Truth. But if some extraneous consideration or some psychological complication comes in his way and, under its influence, he refuses to accept the Truth, he then starts devising ways and means of justifying his rejection of it and tries to prove that his bad deeds are actually good deeds. Those who suffer from such psychological barriers never admit the Truth. It is only when, after death, they come face to face with God that they reap what they have sown.
