﴿ أَمْ ءَاتَيْنَٰهُمْ كِتَٰبًۭا مِّن قَبْلِهِۦ فَهُم بِهِۦ مُسْتَمْسِكُونَ ﴾

“Or have We, perchance, vouchsafed them, before this one, a revelation [to the contrary,] to which they are still holding fast?”

(Or have We given them any Scripture before) this Qur'an (so that they are holding fast thereto) so that they take such a belief from this Scripture?
