Quran 34:14 Saba, ayah 14 of 54

فَلَمَّا قَضَيْنَا عَلَيْهِ ٱلْمَوْتَ مَا دَلَّهُمْ عَلَىٰ مَوْتِهِۦٓ إِلَّا دَآبَّةُ ٱلْأَرْضِ تَأْكُلُ مِنسَأَتَهُۥ ۖ فَلَمَّا خَرَّ تَبَيَّنَتِ ٱلْجِنُّ أَن لَّوْ كَانُوا۟ يَعْلَمُونَ ٱلْغَيْبَ مَا لَبِثُوا۟ فِى ٱلْعَذَابِ ٱلْمُهِينِ ۝١٤

34:14 And when We decreed death for him, nothing showed his death to them save a creeping creature of the earth which gnawed away his staff. And when he fell the jinn saw clearly how, if they had known the Unseen, they would not have continued in despised toil.
