﴿ أَمْ أَمِنتُم مَّن فِى ٱلسَّمَآءِ أَن يُرْسِلَ عَلَيْكُمْ حَاصِبًۭا ۖ فَسَتَعْلَمُونَ كَيْفَ نَذِيرِ ﴾

“Or can you ever feel secure that He who is in heaven will not let loose against you a deadly stormwind, whereupon you would come to know how [true] My warning was?”

Are you secure in thinking that He Who is in the heaven will not unleash an yursila substitutes for man ‘He Who’ upon you a squall of pebbles? a wind hurling pebbles at you. But you will soon come to know upon seeing the chastisement with your own eyes the nature of My warning My warning of chastisement in other words you will soon see that it was true.
