Sura al-Shuʿarā 26:4

إِن نَّشَأْ نُنَزِّلْ عَلَيْهِم مِّنَ ٱلسَّمَآءِ ءَايَةً فَظَلَّتْ أَعْنَٰقُهُمْ لَهَا خَٰضِعِينَ

in nashaʾ nunazzil ʿalayhim mina l-samāʾi āyatan fa-ẓallat aʿnāquhum lahā khāḍiʿīna

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.
