﴿ وَقَالَ ٱلَّذِينَ أُوتُوا۟ ٱلْعِلْمَ وَٱلْإِيمَٰنَ لَقَدْ لَبِثْتُمْ فِى كِتَٰبِ ٱللَّهِ إِلَىٰ يَوْمِ ٱلْبَعْثِ ۖ فَهَٰذَا يَوْمُ ٱلْبَعْثِ وَلَٰكِنَّكُمْ كُنتُمْ لَا تَعْلَمُونَ ﴾
“But those who [in their lifetime] were endowed with knowledge and faith will say: “Indeed, you have been tardy in [accepting as true] what God has revealed, [and you have waited] until the Day of Resurrection: this, then, is the Day of Resurrection: but you - you were determined not to know it!”
