أَلَا يَعْلَمُ مَنْ خَلَقَ وَهُوَ ٱللَّطِيفُ ٱلْخَبِيرُ
Does He who created not know, while He is the Subtle, the Acquainted?
هُوَ ٱلَّذِى جَعَلَ لَكُمُ ٱلْأَرْضَ ذَلُولًا فَٱمْشُوا۟ فِى مَنَاكِبِهَا وَكُلُوا۟ مِن رِّزْقِهِۦ ۖ وَإِلَيْهِ ٱلنُّشُورُ
It is He who made the earth tame for you - so walk among its slopes and eat of His provision - and to Him is the resurrection.
أَمْ أَمِنتُم مَّن فِى ٱلسَّمَآءِ أَن يُرْسِلَ عَلَيْكُمْ حَاصِبًا ۖ فَسَتَعْلَمُونَ كَيْفَ نَذِيرِ
Or do you feel secure that He who [holds authority] in the heaven would not send against you a storm of stones? Then you would know how [severe] was My warning.
وَلَقَدْ كَذَّبَ ٱلَّذِينَ مِن قَبْلِهِمْ فَكَيْفَ كَانَ نَكِيرِ
And already had those before them denied, and how [terrible] was My reproach.
