Verse 17

أَفَمَن كَانَ عَلَىٰ بَيِّنَةٍ مِّن رَّبِّهِۦ وَيَتْلُوهُ شَاهِدٌ مِّنْهُ وَمِن قَبْلِهِۦ كِتَـٰبُ مُوسَىٰٓ إِمَامًا وَرَحْمَةً أُو۟لَـٰٓئِكَ يُؤْمِنُونَ بِهِۦ وَمَن يَكْفُرْ بِهِۦ مِنَ ٱلْأَحْزَابِ فَٱلنَّارُ مَوْعِدُهُۥ فَلَا تَكُ فِى مِرْيَةٍ مِّنْهُ إِنَّهُ ٱلْحَقُّ مِن رَّبِّكَ وَلَـٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يُؤْمِنُونَ

Then who is the one who stands firm by a proof from his Lord? A witness did recite it previously in Moses’ scripture, a leading authority as well as a mercy.  They did believe in it. As for those who disbelieved it among various parties, then Hell is promised to them. As for you, you shall not have any doubt about it. Indeed this is the truth from your Lord, however, most people will not attain faith.
