Surah As-Saf (The Solid Ranks), Verse 7

وَمَنْ اَظْلَمُ مِمَّنِ افْتَرٰی عَلَی اللّٰهِ الْكَذِبَ وَهُوَ یُدْعٰۤی اِلَی الْاِسْلَامِ وَاللّٰهُ لَا یَهْدِی الْقَوْمَ الظّٰلِمِیْنَ ۟

Wa man azlamu mimma nif taraa 'alal laahil kaziba wa huwa yad'aaa ilal Islaam; wallaahu laa yahdil qawmaz zaalimeen

“Who doth greater wrong than one who invents falsehood against Allah, even as he is being invited to Islam? And Allah guides not those who do wrong.”

Quran 61:7 (Yusuf Ali Translation)
