11

And among mankind there are those who worship Allahu ta’ālā on a knife-edge: that is, with uncertainty in his worship - such [a person] has been likened the [knife-] edge of a mountain in his precariousness - if good [fortune] befalls him, [so that he enjoys] health and security with respect to his own self and his property, he is reassured by it; but if an ordeal befalls him, a trial or ill-health with regard to himself or his property, he makes a turnabout, that is, he reverts to disbelief, losing both this world, when what he had hoped for in it has eluded him, and the Hereafter, by [his] disbelief. That is the manifest loss.
