The Quran

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

(Saheeh International)

And when We decreed for him [i.e., Solomon] death, nothing indicated to them [i.e., the jinn] his death except a creature of the earth eating his staff.¹ 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.²

Upon which he was leaning at the time of his death. A termite continued to gnaw into the stick until it collapsed under his weight.
i.e., hard labor. This verse is evidence that the jinn do not possess knowledge of the unseen, which belongs exclusively to Allāh (subḥānahu wa ta‘ālā).
