﴿ فَلَمَّا جَآءَتْهُمْ رُسُلُهُم بِٱلْبَيِّنَٰتِ فَرِحُوا۟ بِمَا عِندَهُم مِّنَ ٱلْعِلْمِ وَحَاقَ بِهِم مَّا كَانُوا۟ بِهِۦ يَسْتَهْزِءُونَ ﴾
“for when their apostles came to them with all evidence of the truth, they arrogantly exulted in whatever knowledge they [already] possessed: and [so, in the end,] they were overwhelmed by the very thing which they were wont to deride.”
