Allah is never unaware of what His servants do: these verses stress this repeatedly. They also describe the heedless, whom worldly life turns away from the truth and the Hereafter, foretell their woe when death awakens them, and warn against obeying one whose heart is heedless of Allah’s remembrance.
Verses gathered from a topical index of the Quran, in Mushaf order; every verse is quoted in full.
And warn them, [O Muḥammad], of the Day of Regret, when the matter will be concluded; and [yet], they are in [a state of] heedlessness, and they do not believe.
And [when] the true promise [i.e., the resurrection] has approached; then suddenly the eyes of those who disbelieved will be staring [in horror, while they say], "O woe to us; we had been unmindful of this; rather, we were wrongdoers."
