As Saff, 7 Ayah
61:7
وَمَنۡ أَظۡلَمُ مِمَّنِ ٱفۡتَرَىٰ عَلَى ٱللَّهِ ٱلۡكَذِبَ وَهُوَ يُدۡعَىٰٓ إِلَى ٱلۡإِسۡلَٰمِۚ وَٱللَّهُ لَا يَهۡدِي ٱلۡقَوۡمَ ٱلظَّٰلِمِينَ ٧
Wa Man 'Ažlamu Mimmani Aftará `Alá Al-Lahi Al-Kadhiba Wa Huwa Yud`á 'Ilá Al-'Islāmi Wa ۚ Allāhu Lā Yahdī Al-Qawma Až-Žālimīna
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.
