righteous conduct (ihsan)

وَإِن كُنتُنَّ تُرِدْنَ ٱللَّهَ وَرَسُولَهُۥ وَٱلدَّارَ ٱلْـَٔاخِرَةَ فَإِنَّ ٱللَّهَ أَعَدَّ لِلْمُحْسِنَـٰتِ مِنكُنَّ أَجْرًا عَظِيمًا

But if you should desire Allāh and His Messenger and the home of the Hereafter - then indeed, Allāh has prepared for the doers of good among you a great reward."
