As-Saf 7

وَمَنْ أَظْلَمُ مِمَّنِ ٱفْتَرَىٰ عَلَى ٱللَّهِ ٱلْكَذِبَ وَهُوَ يُدْعَىٰٓ إِلَى ٱلْإِسْلَـٰمِ ۚ وَٱللَّهُ لَا يَهْدِى ٱلْقَوْمَ ٱلظَّـٰلِمِينَ

waman aẓlamu mimmani if'tarā ʿalā l-lahi l-kadhiba wahuwa yud'ʿā ilā l-is'lāmi wal-lahu lā yahdī l-qawma l-ẓālimīna

And who is more unjust than one who invents about Allāh untruth while he is being invited to Islām. And Allāh does not guide the wrongdoing people.
