so when they behold the existence pervading created things, this existence becomes manifest to them, and they imagine it to be Allah. They therefore call created things loci of manifestation and disclosure, because they reveal to them what they imagine to be Allah.
Had they instead regarded them as signs that revealed and clarified for them what they indicated in various respects, as well as His knowledge, power, mercy, and wisdom—while knowing that His existence is distinct from theirs—they would have been rightly guided.
