Sura Hūd 11:35

أَمْ يَقُولُونَ ٱفْتَرَىٰهُ قُلْ إِنِ ٱفْتَرَيْتُهُۥ فَعَلَىَّ إِجْرَامِى وَأَنَا۠ بَرِىٓءٌ مِّمَّا تُجْرِمُونَ

am yaqūlūna iftarāhu qul ini iftaraytuhu faʿalaya ijrāmī wa-anā barīʾun mimmā tujrimūna

Or do they say, "He has forged it"? Say: "If I had forged it, on me were my sin! and I am free of the sins of which ye are guilty!
