Surah Hud, Verse 18
وَمَنْ أَظْلَمُ مِمَّنِ ٱفْتَرَىٰ عَلَى ٱللَّهِ كَذِبًا ۚ أُو۟لَٰٓئِكَ يُعْرَضُونَ عَلَىٰ رَبِّهِمْ وَيَقُولُ ٱلْأَشْهَٰدُ هَٰٓؤُلَآءِ ٱلَّذِينَ كَذَبُوا۟ عَلَىٰ رَبِّهِمْ ۚ أَلَا لَعْنَةُ ٱللَّهِ عَلَى ٱلظَّٰلِمِينَ
Translation — Sahih International
And who is more unjust than he who invents a lie about Allah? Those will be presented before their Lord, and the witnesses will say, "These are the ones who lied against their Lord." Unquestionably, the curse of Allah is upon the wrongdoers.
