We would have invented against Allah a lie if we returned to (7:89)

﴿قَدِ افْتَرَيْنَا عَلَى اللَّهِ كَذِبًا إِنْ عُدْنَا فِي مِلَّتِكُم بَعْدَ إِذْ نَجَّانَا اللَّهُ مِنْهَا ۚ وَمَا يَكُونُ لَنَا أَن نَّعُودَ فِيهَا إِلَّا أَن يَشَاءَ اللَّهُ رَبُّنَا ۚ وَسِعَ رَبُّنَا كُلَّ شَيْءٍ عِلْمًا ۚ عَلَى اللَّهِ تَوَكَّلْنَا ۚ رَبَّنَا افْتَحْ بَيْنَنَا وَبَيْنَ قَوْمِنَا بِالْحَقِّ وَأَنتَ خَيْرُ الْفَاتِحِينَ﴾
[ الأعراف: 89]

7:89 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."

'If we follow what you believe of disbelief and polytheism after we have been saved from it by Allah’s grace, we would have invented a lie against Him.
It would not be appropriate or right for us to return to your false religion unless Allah wills us to do so – as we will do whatever He wills.
Allah surrounds everything in knowledge, and so He knows what is right for His slaves.
Nothing is hidden from Him.
We put our trust in Allah alone, so He will make us firm on the right path and protect us from the ways leading to Hell.
O our Lord! Judge between us and these disbelieving people with the truth, and help those who hold to the truth and those who are wronged against those who are wrongdoers.
You O Lord are the best of Judges.
'.

"We should have invented a lie against Allah if we returned to your religion, after Allah has rescued us from it. And it is not for us to return to it unless Allah, our Lord, should will. Our Lord comprehends all things in His Knowledge. In Allah (Alone) we put our trust. Our Lord! Judge between us and our people in truth, for You are the Best of those who give judgment."
