أَمْ آتَيْنَاهُمْ كِتَابًا مِّن قَبْلِهِ فَهُم بِهِ مُسْتَمْسِكُونَ
[43:21]
Or have We given them a book before it so that they hold fast to it?
What! have We given them a Book before this, to which they are holding fast?
Or have We given them any scripture before (this Qur'an) so that they are holding fast thereto?
