Quran 29:41 — The Spider (Al-'Ankaboot)

The allegory of those who accept other masters beside GOD is that of the spider and her home; the flimsiest of all homes is the home of the spider, if they only knew.*

[29:40] All those disbelievers were doomed as a consequence of their sins. Some of them we annihilated by violent winds, some were annihilated by the quake, some we caused the earth to swallow, and some we drowned. GOD is not the One who wronged them; it is they who wronged their own souls.

[29:42] GOD knows full well that whatever they worship beside Him are really nothing. He is the Almighty, the Most Wise.
