هَلْ يَنظُرُونَ إِلَّا أَن تَأْتِيَهُمُ الْمَلَائِكَةُ أَوْ يَأْتِيَ أَمْرُ رَبِّكَ ۚ كَذَٰلِكَ فَعَلَ الَّذِينَ مِن قَبْلِهِمْ ۚ وَمَا ظَلَمَهُمُ اللَّهُ وَلَٰكِن كَانُوا أَنفُسَهُمْ يَظْلِمُونَ (33)
(16:33) (O Muhammad!) are these people still waiting, though now nothing has been left but that angels should come or your Lord's judgment be passed on them? *29 Many people before them behaved audaciously like them, and had to take the consequence: it was not Allah Who was unjust to them but they were unjust to themselves.
*29) This is to admonish the unbelievers to this effect: "Why are they still hesitating to accept the Message which is very simple and clear ? We have tried every method to present each aspect of the Truth clearly with arguments and brought witnesses thereof from the whole system of the universe, and have left no room for any man of understanding to stick to shirk. Now what they are waiting for is nothing more than this that the angel of death should come before them: and then they will accept the Message at the last moment of their lives. Or, do they wait for the scourge of God to overtake them and make them accept the Message?"
