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
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.
