Al-Kahf (The Cave)
Surah 18 · Verse 57
And who is more unjust than he who is reminded through the signs of his Fosterer but he turns away from them and forgets what his hands have sent forth ? We have certainly placed veils over their hearts lest they should understand the (Quran) and heaviness in their ears, and if you invite them towards guidance, even then they will not accept guidance for ever.
Allah (SWT) seals the receptive powers of some unjust people, therefore they turn away from His message and forget their sins for which they will be punished at an appointed time as was done earlier with such people of many towns.
