Quran 34:14 from Surah Saba on Divine Marvels.
فَلَمَّا قَضَيۡنَا عَلَيۡهِ ٱلۡمَوۡتَ مَا دَلَّهُمۡ عَلَىٰ مَوۡتِهِۦٓ إِلَّا دَآبَّةُ ٱلۡأَرۡضِ تَأۡكُلُ مِنسَأَتَهُۥۖ فَلَمَّا خَرَّ تَبَيَّنَتِ ٱلۡجِنُّ أَن لَّوۡ كَانُواْ يَعۡلَمُونَ ٱلۡغَيۡبَ مَا لَبِثُواْ فِي ٱلۡعَذَابِ ٱلۡمُهِينِ
English translation: Then when We decreed for him the death not indicated to them [on] his death except a creature (of) the earth eating his staff But when he fell down became clear (to) the jinn that if they had known the unseen not they (would have) remained in the punishment humiliating
Transliteration: falamma qadayna alayhi al-mawta ma dallahum ala mawtihi illa dabbatu al-ardi takulu minsa-atahu falamma kharra tabayyanati al-jinu an law kanu ya'lamuna al-ghayba ma labithu fi al-'adhabi al-muhini
