Verse 116

إِنَّ ٱللَّهَ لَا يَغْفِرُ أَن يُشْرَكَ بِهِۦ وَيَغْفِرُ مَا دُونَ ذَٰلِكَ لِمَن يَشَآءُ وَمَن يُشْرِكْ بِٱللَّهِ فَقَدْ ضَلَّ ضَلَـٰلًۢا بَعِيدًا

Indeed God does not forgive setting up a partner for Him and forgives lesser offenses for whomever He wills. Furthermore, whoever sets up partners for God has indeed strayed, far astray.
