AL MU'MIN — Ayat 83

فَلَمَّا جَاءتْهُمْ رُسُلُهُم بِالْبَيِّنَاتِ فَرِحُوا بِمَا عِندَهُم مِّنَ الْعِلْمِ وَحَاقَ بِهِم مَّا كَانُوا بِهِ يَسْتَهْزِئُون

And when their messengers came to them with clear proofs, they [merely] rejoiced in what they had of knowledge, but they were enveloped by what they used to ridicule.
