قَدِ ٱفْتَرَيْنَا عَلَى ٱللَّهِ كَذِبًا إِنْ عُدْنَا فِى مِلَّتِكُم بَعْدَ إِذْ نَجَّىٰنَا ٱللَّهُ مِنْهَا ۚ وَمَا يَكُونُ لَنَآ أَن نَّعُودَ فِيهَآ إِلَّآ أَن يَشَآءَ ٱللَّهُ رَبُّنَا ۚ وَسِعَ رَبُّنَا كُلَّ شَىْءٍ عِلْمًا ۚ عَلَى ٱللَّهِ تَوَكَّلْنَا ۚ رَبَّنَا ٱفْتَحْ بَيْنَنَا وَبَيْنَ قَوْمِنَا بِٱلْحَقِّ وَأَنتَ خَيْرُ ٱلْفَـٰتِحِينَ 89

We would have invented against Allāh a lie if we returned to your religion after Allāh had saved us from it. And it is not for us to return to it except that Allāh, our Lord, should will. Our Lord has encompassed all things in knowledge. Upon Allāh we have relied. Our Lord, decide between us and our people in truth, and You are the best of those who give decision."
