﴿ إِلَّا ٱلَّذِينَ تَابُوا۟ مِن قَبْلِ أَن تَقْدِرُوا۟ عَلَيْهِمْ ۖ فَٱعْلَمُوٓا۟ أَنَّ ٱللَّهَ غَفُورٌۭ رَّحِيمٌۭ ﴾

“save for such [of them] as repent ere you [O believers] become more powerful than they: for you must know that God is much-forgiving, a dispenser of grace.”

The greatest achievement for a man is his nearness to God. This nearness in its real and perfect shape will be his in the Hereafter. However, when a man’s righteous action brings him nearness to God, he experiences this in this world purely in the form of heavenly feeling. The way to attain this nearness is through becoming a true worshipper of God, and through struggling to make efforts for His cause.
