Quran 7, Al-A'raf (The Heights) ⓘ

7:89We should have invented a lie against Allah if we returned to your religion after Allah hath rescued us from it. It is not for us to return to it unless Allah our Lord should (so) will. Our Lord comprehendeth all things in knowledge. In Allah do we put our trust. Our Lord! Decide with truth between us and our folk, for Thou art the best of those who make decision.

قَدِ افْتَرَيْنَا عَلَى اللَّهِ كَذِبًا إِنْ عُدْنَا فِي مِلَّتِكُمْ بَعْدَ إِذْ نَجَّانَا اللَّهُ مِنْهَا وَمَا يَكُونُ لَنَا أَنْ نَعُودَ فِيهَا إِلَّا أَنْ يَشَاءَ اللَّهُ رَبُّنَا وَسِعَ رَبُّنَا كُلَّ شَيْءٍ عِلْمًا عَلَى اللَّهِ تَوَكَّلْنَا رَبَّنَا افْتَحْ بَيْنَنَا وَبَيْنَ قَوْمِنَا بِالْحَقِّ وَأَنْتَ خَيْرُ الْفَاتِحِينَ
