SABA' (KAUM SABA') — Ayat 14
فَلَمَّا قَضَيْنَا عَلَيْهِ الْمَوْتَ مَا دَلَّهُمْ عَلَى مَوْتِهِ إِلَّا دَابَّةُ الْأَرْضِ تَأْكُلُ مِنسَأَتَهُ فَلَمَّا خَرَّ تَبَيَّنَتِ الْجِنُّ أَن لَّوْ كَانُوا يَعْلَمُونَ الْغَيْبَ مَا لَبِثُوا فِي الْعَذَابِ الْمُهِينِ
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.
Tafsir
{So when We decreed for him} Solomon {death}, that is, he died and remained standing on his staff for a year, dead, and the jinn were doing those hard jobs as usual, not noticing his death until the termites ate his staff and he fell down dead. {Nothing informed them of his death except a creature of the earth}, the source of the verb adrata, in the passive form, eaten by the termites {eating his staff} with a hamza and leaving it with the alif of his staff because it is used to drive away and repel. {So when he fell down} dead, {the jinn realized} it was revealed to them that {had they known the unseen}, including what was hidden from them about Solomon’s death {they would not have remained in the humiliating punishment}, the hard work for them because they thought he was alive, contrary to their thought. Knowledge of the unseen and knowledge that it is a year, based on the calculation of what the termites ate of the staff after his death, for example, a day and a night.
