Dr. Mustafa Khattab, the Clear Quran - Surah Al-Mu'minun, ayah 68

Translation of Surah Al-Mu'minun, ayah 68 (23:68)

أَفَلَمۡ يَدَّبَّرُواْ ٱلۡقَوۡلَ أَمۡ جَآءَهُم مَّا لَمۡ يَأۡتِ ءَابَآءَهُمُ ٱلۡأَوَّلِينَ ٦٨
Is it because they have never contemplated the Word ˹of Allah˺? Or ˹because˺ there has come to them something that did not come to their forefathers?
