An-Nisa' - 4:113

وَلَوْلاَ فَضْلُ اللّهِ عَلَيْكَ وَرَحْمَتُهُ لَهَمَّت طَّآئِفَةٌ مُّنْهُمْ أَن يُضِلُّوكَ وَمَا يُضِلُّونَ إِلاُّ أَنفُسَهُمْ وَمَا يَضُرُّونَكَ مِن شَيْءٍ وَأَنزَلَ اللّهُ عَلَيْكَ الْكِتَابَ وَالْحِكْمَةَ وَعَلَّمَكَ مَا لَمْ تَكُنْ تَعْلَمُ وَكَانَ فَضْلُ اللّهِ عَلَيْكَ عَظِيمًا
[4:113]
And were it not for Allah's grace upon you and His mercy a party of them had certainly designed to bring you to perdition and they do not bring (aught) to perdition but their own souls, and they shall not harm you in any way, and Allah has revealed to you the Book and the wisdom, and He has taught you what you did not know, and Allah's grace on you is very great.
But for the Grace of Allah to thee and his Mercy, a party of them would certainly have plotted to lead thee astray. But (in fact) they will only Lead their own souls astray, and to thee they can do no harm in the least. For Allah hath sent down to thee the Book and wisdom and taught thee what thou Knewest not (before): And great is the Grace of Allah unto thee.
But for the grace of Allah upon thee (Muhammad), and His mercy, a party of them had resolved to mislead thee, but they will mislead only themselves and they will hurt thee not at all. Allah revealeth unto thee the Scripture and wisdom, and teacheth thee that which thou knewest not. The grace of Allah toward thee hath been infinite.
