﴿ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ ٱتَّقُوا۟ ٱللَّهَ وَٱبْتَغُوٓا۟ إِلَيْهِ ٱلْوَسِيلَةَ وَجَٰهِدُوا۟ فِى سَبِيلِهِۦ لَعَلَّكُمْ تُفْلِحُونَ ﴾

“O YOU who have attained to faith! Remain conscious of God, and seek to come closer unto Him, and strive hard in His cause, so that you might attain to a happy state.”

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.
