إِن نَّشَأْ نُنَزِّلْ عَلَيْهِم مِّن السَّمَاء آيَةً فَظَلَّتْ أَعْنَاقُهُمْ لَهَا خَاضِعِينَ
[26:4]
If We please, We should send down upon them a sign from the heaven so that their necks should stoop to it.
If (such) were Our Will, We could send down to them from the sky a Sign, to which they would bend their necks in humility.
If We will, We can send down on them from the sky a portent so that their necks would remain bowed before it.
