And among people are some who serve Allah conditionally, standing on the brink or border, as it were, between faith without and infidelity within. If all goes well with any of them and he makes worldly gains he is gratified and he advances without and to his heart's content. And should he be tested for true belief and inclination and he is consequently befallen with a misfortune or wedded to a calamity he retracts and retreats within, he tumbles down on his face and turns renegade wherefore he loses both worlds, here and Hereafter, And this is indeed the utmost loss.
