Qur'an 6:93

وَمَنْ أَظْلَمُ مِمَّنِ ٱفْتَرَىٰ عَلَى ٱللَّهِ كَذِبًا أَوْ قَالَ أُوحِىَ إِلَىَّ وَلَمْ يُوحَ إِلَيْهِ شَىْءٌ وَمَن قَالَ سَأُنزِلُ مِثْلَ مَآ أَنزَلَ ٱللَّهُ ۗ وَلَوْ تَرَىٰٓ إِذِ ٱلظَّـٰلِمُونَ فِى غَمَرَٰتِ ٱلْمَوْتِ وَٱلْمَلَـٰٓئِكَةُ بَاسِطُوٓا۟ أَيْدِيهِمْ أَخْرِجُوٓا۟ أَنفُسَكُمُ ۖ ٱلْيَوْمَ تُجْزَوْنَ عَذَابَ ٱلْهُونِ بِمَا كُنتُمْ تَقُولُونَ عَلَى ٱللَّهِ غَيْرَ ٱلْحَقِّ وَكُنتُمْ عَنْ ءَايَـٰتِهِۦ تَسْتَكْبِرُونَ

Who is guilty of more wrong than he who forgeth a lie against Allah, or saith: I am inspired, when he is not inspired in aught; and who saith: I will reveal the like of that which Allah hath revealed? If thou couldst see, when the wrong-doers reach the pangs of death and the angels stretch their hands out (saying): Deliver up your souls. This day ye are awarded doom of degradation for that ye spake concerning Allah other than the truth, and used to scorn His portents.
