﴿ وَمَن كَفَرَ فَلَا يَحْزُنكَ كُفْرُهُۥٓ ۚ إِلَيْنَا مَرْجِعُهُمْ فَنُنَبِّئُهُم بِمَا عَمِلُوٓا۟ ۚ إِنَّ ٱللَّهَ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ ﴾

“But as for him who is bent on denying the truth - let not his denial grieve thee: unto Us they must return, and then We shall make them [truly] understand all that they were doing [in life]: for, verily, God has full knowledge of what is in the hearts [of men].”

Every man’s nature has a direction in which he, along with his whole thought, action and his very existence, is inclined. The believer is one whose direction is entirely towards God. The life of a believer is a completely God-oriented life, and an unbeliever’s life is a non-God-oriented life. One who turns towards God is going in fact in the direction of the right goal, where he will find success. On the contrary, one who becomes neglectful of God and diverts his attention towards someone other than God becomes direction-less and goal-less. He may receive some temporary benefits for the time being but, in the permanent life of the Hereafter, there will be nothing for him except punishment.
