أَمْ أَمِنتُم مَّن فِى ٱلسَّمَآءِ أَن يُرْسِلَ عَلَيْكُمْ حَاصِبًا ۖ فَسَتَعْلَمُونَ كَيْفَ نَذِيرِ
Am amintum man fissamaaa'i ai yursila 'alaikum haasiban fasata'lamoona kaifa nazeer
Are you sure that He who is in Heaven will not send a whirlwind to pelt you with stones? You will come to know what My warning means.
Or do you feel secure that the one in the heaven will not send against you a storm of stones? Then you will know how my warning was.
