A Man Swallowed by the Earth, and a Web as Fragile as Its Weaver's Trust

Hizb 40 closes Al-Qasas by contrasting receptive listeners among the People of the Book with Pharaoh's outright rejection, then tells the story of Qarun, a wealthy man from Moses's own people who grows arrogant over his riches, insisting he earned them through his own knowledge alone, before the earth swallows him and his household as a consequence, a warning against crediting success purely to personal skill rather than to what has been given. The sura closes reassuring the Prophet of an eventual return to his birthplace and warning against relying on disbelievers' support.

The hizb then opens Al-Ankabut, the Spider, with a widely quoted opening test: whether people imagine they will be left merely to say they believe without being tried by anything at all. It compares those who take protectors other than God to the spider building its own house, the frailest house of all, a fragility the sura applies directly to any security sought outside reliance on God.

The hizb closes with compressed retellings of Noah, Abraham's confrontation with his idol worshipping people and his survival of the fire, and Lot, offered as reassurance to a besieged early community that hardship has preceded every prophet's eventual success rather than ever being proof of failure.
