﴿ وَمَنْ أَظْلَمُ مِمَّنِ ٱفْتَرَىٰ عَلَى ٱللَّهِ كَذِبًا ۚ أُو۟لَٰٓئِكَ يُعْرَضُونَ عَلَىٰ رَبِّهِمْ وَيَقُولُ ٱلْأَشْهَٰدُ هَٰٓؤُلَآءِ ٱلَّذِينَ كَذَبُوا۟ عَلَىٰ رَبِّهِمْ ۚ أَلَا لَعْنَةُ ٱللَّهِ عَلَى ٱلظَّٰلِمِينَ ﴾

“And who could be more wicked than they who attribute their own lying inventions to God? [On the Day of Judgment, such as] these shall be arraigned before their Sustainer, and those who are called upon to bear witness [against them] shall say, "It is they who uttered lies about their Sustainer!" Oh, verily, God's rejection is the due of all evildoers”
