29:6
وَمَن جَٰهَدَ فَإِنَّمَا يُجَٰهِدُ لِنَفْسِهِۦٓ ۚ إِنَّ ٱللَّهَ لَغَنِىٌّ عَنِ ٱلْعَٰلَمِينَ
Wa man jaahada fainnamaa yujaahidu linafsih; innal laaha laghaniyyun 'anil 'aalameen
And whoever strives hard, he strives only for his own soul; most surely Allah is Self-sufficient, above (need of) the worlds.
