بَلِ ٱدَّٰرَكَ عِلۡمُهُمۡ فِي ٱلۡأٓخِرَةِۚ بَلۡ هُمۡ فِي شَكّٖ مِّنۡهَاۖ بَلۡ هُم مِّنۡهَا عَمُونَ ٦٦
Rather, their knowledge is arrested concerning the Hereafter. Rather, they are in doubt about it. Rather, they are, concerning it, blind.
Translation: Saheeh International (English)
Each word's meaning and sound
But rather their knowledge in the afterlife will become complete, due to their seeing it with their own eyes after the Messengers used to inform them of it when it was unseen, but they used to deny it because they had not seen it. And they were in doubt and confusion regarding the afterlife in their worldly life, for their eyes and hearts had become blind towards it.
