Quran As-Saf 61:7

وَمَنۡ أَظۡلَمُ مِمَّنِ ٱفۡتَرَىٰ عَلَى ٱللَّهِ ٱلۡكَذِبَ وَهُوَ يُدۡعَىٰٓ إِلَى ٱلۡإِسۡلَٰمِۚ وَٱللَّهُ لَا يَهۡدِي ٱلۡقَوۡمَ ٱلظَّٰلِمِينَ

Translation

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.
