Surah 29. Al-Ankabut, Ayah 66

The particle li prefixed to the subsequent verbs yakfuru ("they show [utter] ingratitude") and yatamatta'u ("they enjoy [or "go on enjoying"] their worldly life") is not an indication of intent ("so that" or "in order that") but merely of a causal sequence; in the above context, it may be appropriately rendered as "and thus".

Such folly results in the virtual rejection (even though it may not be express) of Allah and His Grace. It plunges man into the pleasures and vanities that merely delude and are bound to pass away. This delusion, however, will come to an end when the true Reality of the Hereafter will shine forth in all its splendor.
