فَلَمّا قَضَينا عَلَيهِ المَوتَ ما دَلَّهُم عَلىٰ مَوتِهِ إِلّا دابَّةُ الأَرضِ تَأكُلُ مِنسَأَتَهُ ۖ فَلَمّا خَرَّ تَبَيَّنَتِ الجِنُّ أَن لَو كانوا يَعلَمونَ الغَيبَ ما لَبِثوا فِي العَذابِ المُهينِ

And when We decreed for Solomon death, nothing indicated to the jinn his death except a creature of the earth eating his staff. But when he fell, it became clear to the jinn that if they had known the unseen, they would not have remained in humiliating punishment.
