An-Najm 53:39
وَأَن لَّيْسَ لِلْإِنسَـٰنِ إِلَّا مَا سَعَىٰ
Waan laysa lil-insani illa masaAAa
"And that there is not for man except that [good] for which he strives"
An-Najm 53:39, translation by Sahih International
A short reflection
Man has nothing but what he strives for. His striving will be seen, and he will be repaid for it in full.
