consequences of rejecting signs

أَمْ أَمِنتُمْ أَن يُعِيدَكُمْ فِيهِ تَارَةً أُخْرَىٰ فَيُرْسِلَ عَلَيْكُمْ قَاصِفًا مِّنَ ٱلرِّيحِ فَيُغْرِقَكُم بِمَا كَفَرْتُمْ ۙ ثُمَّ لَا تَجِدُوا۟ لَكُمْ عَلَيْنَا بِهِۦ تَبِيعًا

Or do you feel secure that He will not send you back into it [i.e., the sea] another time and send upon you a hurricane of wind and drown you for what you denied? Then you would not find for yourselves against Us an avenger.

۞ وَلَوْ رَحِمْنَـٰهُمْ وَكَشَفْنَا مَا بِهِم مِّن ضُرٍّ لَّلَجُّوا۟ فِى طُغْيَـٰنِهِمْ يَعْمَهُونَ

And even if We gave them mercy and removed what was upon them of affliction, they would persist in their transgression, wandering blindly.

كَذَٰلِكَ ٱلْعَذَابُ ۖ وَلَعَذَابُ ٱلْـَٔاخِرَةِ أَكْبَرُ ۚ لَوْ كَانُوا۟ يَعْلَمُونَ

Such is the punishment [of this world]. And the punishment of the Hereafter is greater, if they only knew.
