Jonah
وَمَا كَانَ هَـٰذَا ٱلْقُرْءَانُ أَن يُفْتَرَىٰ مِن دُونِ ٱللَّهِ وَلَـٰكِن تَصْدِيقَ ٱلَّذِى بَيْنَ يَدَيْهِ وَتَفْصِيلَ ٱلْكِتَـٰبِ لَا رَيْبَ فِيهِ مِن رَّبِّ ٱلْعَـٰلَمِينَ
And it was not [possible] for this Qur'an to be produced by other than Allah, but [it is] a confirmation of what was before it and a detailed explanation of the [former] Scripture, about which there is no doubt, from the Lord of the worlds.
Nearby ayahs help place verse 10:37 in sequence and meaning.
قُلْ هَلْ مِن شُرَكَآئِكُم مَّن يَهْدِىٓ إِلَى ٱلْحَقِّ ۚ قُلِ ٱللَّهُ يَهْدِى لِلْحَقِّ ۗ أَفَمَن يَهْدِىٓ إِلَى ٱلْحَقِّ أَحَقُّ أَن يُتَّبَعَ أَمَّن لَّا يَهِدِّىٓ إِلَّآ أَن يُهْدَىٰ ۖ فَمَا لَكُمْ كَيْفَ تَحْكُمُونَ
Say, "Are there of your 'partners' any who guides to the truth?" Say, "Allah guides to the truth. So is He who guides to the truth more worthy to be followed or he who guides not unless he is guided? Then what is [wrong] with you - how do you judge?"
وَمَا يَتَّبِعُ أَكْثَرُهُمْ إِلَّا ظَنًّا ۚ إِنَّ ٱلظَّنَّ لَا يُغْنِى مِنَ ٱلْحَقِّ شَيْـًٔا ۚ إِنَّ ٱللَّهَ عَلِيمٌۢ بِمَا يَفْعَلُونَ
And most of them follow not except assumption. Indeed, assumption avails not against the truth at all. Indeed, Allah is Knowing of what they do.
أَمْ يَقُولُونَ ٱفْتَرَىٰهُ ۖ قُلْ فَأْتُوا۟ بِسُورَةٍ مِّثْلِهِۦ وَٱدْعُوا۟ مَنِ ٱسْتَطَعْتُم مِّن دُونِ ٱللَّهِ إِن كُنتُمْ صَـٰدِقِينَ
Or do they say [about the Prophet], "He invented it?" Say, "Then bring forth a surah like it and call upon [for assistance] whomever you can besides Allah, if you should be truthful."
بَلْ كَذَّبُوا۟ بِمَا لَمْ يُحِيطُوا۟ بِعِلْمِهِۦ وَلَمَّا يَأْتِهِمْ تَأْوِيلُهُۥ ۚ كَذَٰلِكَ كَذَّبَ ٱلَّذِينَ مِن قَبْلِهِمْ ۖ فَٱنظُرْ كَيْفَ كَانَ عَـٰقِبَةُ ٱلظَّـٰلِمِينَ
Rather, they have denied that which they encompass not in knowledge and whose interpretation has not yet come to them. Thus did those before them deny. Then observe how was the end of the wrongdoers.
