15:24
وَلَقَدْ عَلِمْنَا ٱلْمُسْتَقْدِمِينَ مِنكُمْ وَلَقَدْ عَلِمْنَا ٱلْمُسْتَـْٔخِرِينَ
walaqad ʿalim'nā l-mus'taqdimīna minkum walaqad ʿalim'nā l-mus'takhirīna
We know exactly those of you who come first and those who come later.
And indeed, We know the first generations of you who had passed away, and indeed, We know the present generations of you (mankind), and also those who will come afterwards.
