﴿ وَأَن لَّيْسَ لِلْإِنسَٰنِ إِلَّا مَا سَعَىٰ ﴾

“and that nought shall be accounted unto man but what he is striving for;”

and that wa-an to be understood as wa-annahu man shall have only what he himself strives for of good deeds and so he shall not have anything of the reward for good deeds striven for by another;
