﴿ ذَٰلِكَ بِأَنَّهُمْ كَانَت تَّأْتِيهِمْ رُسُلُهُم بِٱلْبَيِّنَٰتِ فَكَفَرُوا۟ فَأَخَذَهُمُ ٱللَّهُ ۚ إِنَّهُۥ قَوِىٌّۭ شَدِيدُ ٱلْعِقَابِ ﴾

“this, because their apostles had come to them with all evidence of the truth, and yet they rejected it: and so God took them to task - for, verily, He is powerful, severe in retribution!”

That was because their messengers used to bring them clear signs manifest miracles but they disbelieved. So God seized them. Indeed He is Strong Severe in punishment.
