Allah’s Warning to People of the Book:


{ يَٰٓأَيُّهَا ٱلَّذِينَ أُوتُواْ ٱلۡكِتَٰبَ ءَامِنُواْ بِمَا نَزَّلۡنَا مُصَدِّقٗا لِّمَا مَعَكُم مِّن قَبۡلِ أَن نَّطۡمِسَ وُجُوهٗا فَنَرُدَّهَا عَلَىٰٓ أَدۡبَارِهَآ أَوۡ نَلۡعَنَهُمۡ كَمَا لَعَنَّآ أَصۡحَٰبَ ٱلسَّبۡتِۚ وَكَانَ أَمۡرُ ٱللَّهِ مَفۡعُولًا }
[Surah An-Nisāʾ: 47]

Yusuf Ali:
O ye People of the Book! believe in what We have (now) revealed, confirming what was (already) with you, before We change the face and fame of some (of you) beyond all recognition, and turn them hindwards, or curse them as We cursed the Sabbath-breakers, for the decision of Allah Must be carried out.

Since the Holy Qur’an is the only
unadulterated original scripture available to the mankind at present and, unlike other scriptures, did pass the challenge of time and the progress of the human knowledge and is also credited with the Standing Eternal challenge to all concerned:
{ قُل لَّئِنِ ٱجۡتَمَعَتِ ٱلۡإِنسُ وَٱلۡجِنُّ عَلَىٰٓ أَن يَأۡتُواْ بِمِثۡلِ هَٰذَا ٱلۡقُرۡءَانِ لَا يَأۡتُونَ بِمِثۡلِهِۦ وَلَوۡ كَانَ بَعۡضُهُمۡ لِبَعۡضٖ ظَهِيرٗا }
[Surah Al-Isrāʾ: 88]

Mohammed Marmaduke William Pickthall:
Say: Verily, though mankind and the jinn should assemble to produce the like of this Qur'an, they could not produce the like thereof though they were helpers one of another.
Then it is quite reasonable for the people of the Book to take warning very seriously.
