أَمْ أَمِنتُم مَّن فِي السَّمَاء أَن يُرْسِلَ عَلَيْكُمْ حَاصِبًا فَسَتَعْلَمُونَ كَيْفَ نَذِيرِ
[67:17]
Or are you secure of those in the heaven that He should not send down upon you a punishment? Then shall you know how was My warning.
Or do ye feel secure that He Who is in Heaven will not send against you a violent tornado (with showers of stones), so that ye shall know how (terrible) was My warning?
Or have ye taken security from Him Who is in the heaven that He will not let loose on you a hurricane? But ye shall know the manner of My warning.
