Surah 4. An-Nisaa'
Ayah 113
113وَلَوْلَا 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
[113] O Prophet, had not Allah's grace been with you, and had not His .mercy safeguarded you from their mischief, a party from among them had decided to involve you in misunderstanding though they were involving no one but themselves in misunderstanding and could have done you no harm.142 Allah has sent down the Book and the Wisdom to you and taught what you did not know; great indeed is His bounty to you.
142That is,'Even if they had succeeded in deceiving you by making a false report in regard to the case, and in getting your decision in their own favor, they would not have done any harm to you but to themselves, for even in that case they themselves would have been guilty in the sight of Allah, and not you". This is obvious because the real offender is the one who deceives the judge and gets a wrong judgment in his own favor, and not the judge who has to decide the case on the basis of the evidence presented before him. Moreover, such a one might delude himself that he has got "the right" on his side by his cunning devices, but in reality the "real right" remains the `right' in the record of Allah. (See also E.N. 192, Al-Baqarah).
