That is because they defied they opposed God and His Messenger; and whoever defies God indeed God is severe in retribution against him.
- 59:44
ذَٰلِكَ بِأَنَّهُمْ شَاقُّوا اللَّهَ وَرَسُولَهُ ۖ وَمَنْ يُشَاقِّ اللَّهَ فَإِنَّ اللَّهَ شَدِيدُ الْعِقَابِ
For they had opposed God and His Apostle; and whosoever opposes God, then God is severe in retribution.
