أَمْ يُرِيدُونَ كَيْدًا ۖ فَٱلَّذِينَ كَفَرُوا۟ هُمُ ٱلْمَكِيدُونَ
Or do they intend a plan? But those who disbelieve - they are the object of a plan.
أَمْ لَهُمْ إِلَـٰهٌ غَيْرُ ٱللَّهِ ۚ سُبْحَـٰنَ ٱللَّهِ عَمَّا يُشْرِكُونَ
Or have they a deity other than Allah? Exalted is Allah above whatever they associate with Him.
فَذَرْهُمْ حَتَّىٰ يُلَـٰقُوا۟ يَوْمَهُمُ ٱلَّذِى فِيهِ يُصْعَقُونَ
So leave them until they meet their Day in which they will be struck insensible -
يَوْمَ لَا يُغْنِى عَنْهُمْ كَيْدُهُمْ شَيْـًٔا وَلَا هُمْ يُنصَرُونَ
The Day their plan will not avail them at all, nor will they be helped.
