মুহাম্মদ ﷺ কি কুরআন লিখেছিলেন, নাকি পূর্ববর্তী গ্রন্থগুলো থেকে নকল করেছিলেন?

وَمَا كُنتَ تَتۡلُواْ مِن قَبۡلِهِۦ مِن كِتَٰبٖ وَلَا تَخُطُّهُۥ بِيَمِينِكَۖ إِذٗا لَّٱرۡتَابَ ٱلۡمُبۡطِلُونَ

And you did not recite before it any scripture, nor did you inscribe one with your right hand. Then [i.e., otherwise] the falsifiers would have had [cause for] doubt.

وَإِن كُنتُمۡ فِي رَيۡبٖ مِّمَّا نَزَّلۡنَا عَلَىٰ عَبۡدِنَا فَأۡتُواْ بِسُورَةٖ مِّن مِّثۡلِهِۦ وَٱدۡعُواْ شُهَدَآءَكُم مِّن دُونِ ٱللَّهِ إِن كُنتُمۡ صَٰدِقِينَ

And if you are in doubt about what We have sent down [i.e., the Qur’ān] upon Our Servant [i.e., Prophet Muḥammad (ﷺ)], then produce a sūrah the like thereof and call upon your witnesses [i.e., supporters] other than Allāh, if you should be truthful.

قُل لَّئِنِ ٱجۡتَمَعَتِ ٱلۡإِنسُ وَٱلۡجِنُّ عَلَىٰٓ أَن يَأۡتُواْ بِمِثۡلِ هَٰذَا ٱلۡقُرۡءَانِ لَا يَأۡتُونَ بِمِثۡلِهِۦ وَلَوۡ كَانَ بَعۡضُهُمۡ لِبَعۡضٖ ظَهِيرٗا

Say, "If mankind and the jinn gathered in order to produce the like of this Qur’ān, they could not produce the like of it, even if they were to each other assistants."
