Surah An-Nisa, verse 113

وَلَوْلَا فَضْلُ ٱللَّهِ عَلَيْكَ وَرَحْمَتُهُۥ لَهَمَّت طَّآئِفَةٌ مِّنْهُمْ أَن يُضِلُّوكَ وَمَا يُضِلُّونَ إِلَّآ أَنفُسَهُمْ ۖ وَمَا يَضُرُّونَكَ مِن شَىْءٍ ۚ وَأَنزَلَ ٱللَّهُ عَلَيْكَ ٱلْكِتَـٰبَ وَٱلْحِكْمَةَ وَعَلَّمَكَ مَا لَمْ تَكُن تَعْلَمُ ۚ وَكَانَ فَضْلُ ٱللَّهِ عَلَيْكَ عَظِيمًا ﴿١١٣﴾

4:113 Were it not for Allah’s grace and mercy upon you [O Prophet], a group of them would have tried to mislead you, but they only mislead themselves, nor can they harm you in the least. For Allah has sent down to you the Book and Wisdom [Sunnah] and has taught you what you did not know. And the grace of Allah upon you is always great
