Surah Al-A'raaf, Verse 89
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 ٱلْفَٰتِحِينَ
Translation — Sahih International
We would have invented against Allah a lie if we returned to your religion after Allah had saved us from it. And it is not for us to return to it except that Allah, our Lord, should will. Our Lord has encompassed all things in knowledge. Upon Allah we have relied. Our Lord, decide between us and our people in truth, and You are the best of those who give decision."
