هَلْ يَنظُرُونَ إِلَّآ أَن تَأْتِيَهُمُ ٱلْمَلَٰٓئِكَةُ أَوْ يَأْتِىَ أَمْرُ رَبِّكَ ۚ كَذَٰلِكَ فَعَلَ ٱلَّذِينَ مِن قَبْلِهِمْ ۚ وَمَا ظَلَمَهُمُ ٱللَّهُ وَلَٰكِن كَانُوٓا۟ أَنفُسَهُمْ يَظْلِمُونَ
Await they aught say that the angels should come unto them or thy Lord's command should come to pass? Even so did those before them. Allah wronged them not, but they did wrong themselves,
Surah An-Nahl(16:33)
