Divine punishment for disobedience

فَبَدَّلَ ٱلَّذِينَ ظَلَمُوا۟ قَوْلًا غَيْرَ ٱلَّذِى قِيلَ لَهُمْ فَأَنزَلْنَا عَلَى ٱلَّذِينَ ظَلَمُوا۟ رِجْزًا مِّنَ ٱلسَّمَآءِ بِمَا كَانُوا۟ يَفْسُقُونَ

But those who wronged changed [those words] to a statement other than that which had been said to them, so We sent down upon those who wronged a punishment [i.e., plague] from the sky because they were defiantly disobeying.

قَالَ فَإِنَّهَا مُحَرَّمَةٌ عَلَيْهِمْ ۛ أَرْبَعِينَ سَنَةً ۛ يَتِيهُونَ فِى ٱلْأَرْضِ ۚ فَلَا تَأْسَ عَلَى ٱلْقَوْمِ ٱلْفَـٰسِقِينَ

[Allāh] said, "Then indeed, it is forbidden to them for forty years [in which] they will wander throughout the land. So do not grieve over the defiantly disobedient people."
