Surah As-Saff 61:7
وَمَنْ أَظْلَمُ مِمَّنِ ٱفْتَرَىٰ عَلَى ٱللَّهِ ٱلْكَذِبَ وَهُوَ يُدْعَىٰٓ إِلَى ٱلْإِسْلَٰمِ ۚ وَٱللَّهُ لَا يَهْدِى ٱلْقَوْمَ ٱلظَّٰلِمِينَ ٧

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