Qur'an 11:18

وَمَنْ أَظْلَمُ مِمَّنِ ٱفْتَرَىٰ عَلَى ٱللَّهِ كَذِبًا ۚ أُو۟لَـٰٓئِكَ يُعْرَضُونَ عَلَىٰ رَبِّهِمْ وَيَقُولُ ٱلْأَشْهَـٰدُ هَـٰٓؤُلَآءِ ٱلَّذِينَ كَذَبُوا۟ عَلَىٰ رَبِّهِمْ ۚ أَلَا لَعْنَةُ ٱللَّهِ عَلَى ٱلظَّـٰلِمِينَ

“And who is more unjust than he who invents a lie about Allāh? 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 Allāh is upon the wrongdoers.”
