فَلَمَّا جَآءَتْهُمْ رُسُلُهُم بِٱلْبَيِّنَـٰتِ فَرِحُوا۟ بِمَا عِندَهُم مِّنَ ٱلْعِلْمِ وَحَاقَ بِهِم مَّا كَانُوا۟ بِهِۦ يَسْتَهْزِءُونَ

Then when their Messengers came to them with clear proofs, they were glad (and proud) with that which they had of the knowledge (of worldly things). And that at which they used to mock, surrounded them (i.e. the punishment).
