Quranic Authenticity

ذَٰلِكَ مِنْ أَنۢبَآءِ ٱلْغَيْبِ نُوحِيهِ إِلَيْكَ ۖ وَمَا كُنتَ لَدَيْهِمْ إِذْ أَجْمَعُوٓا۟ أَمْرَهُمْ وَهُمْ يَمْكُرُونَ

That is from the news of the unseen which We reveal, [O Muḥammad], to you. And you were not with them when they put together their plan while they conspired.

لَقَدْ كَانَ فِى قَصَصِهِمْ عِبْرَةٌ لِّأُو۟لِى ٱلْأَلْبَـٰبِ ۗ مَا كَانَ حَدِيثًا يُفْتَرَىٰ وَلَـٰكِن تَصْدِيقَ ٱلَّذِى بَيْنَ يَدَيْهِ وَتَفْصِيلَ كُلِّ شَىْءٍ وَهُدًى وَرَحْمَةً لِّقَوْمٍ يُؤْمِنُونَ

There was certainly in their stories a lesson for those of understanding. Never was it [i.e., the Qur’ān] a narration invented, but a confirmation of what was before it and a detailed explanation of all things and guidance and mercy for a people who believe.

قُلْ نَزَّلَهُۥ رُوحُ ٱلْقُدُسِ مِن رَّبِّكَ بِٱلْحَقِّ لِيُثَبِّتَ ٱلَّذِينَ ءَامَنُوا۟ وَهُدًى وَبُشْرَىٰ لِلْمُسْلِمِينَ

Say, [O Muḥammad], "The Pure Spirit [i.e., Gabriel] has brought it down from your Lord in truth to make firm those who believe and as guidance and good tidings to the Muslims."

وَمَا كُنتَ تَتْلُوا۟ مِن قَبْلِهِۦ مِن كِتَـٰبٍ وَلَا تَخُطُّهُۥ بِيَمِينِكَ ۖ إِذًا لَّٱرْتَابَ ٱلْمُبْطِلُونَ

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.

وَعْدَ ٱللَّهِ ۖ لَا يُخْلِفُ ٱللَّهُ وَعْدَهُۥ وَلَـٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يَعْلَمُونَ

[It is] the promise of Allāh. Allāh does not fail in His promise, but most of the people do not know.
