Surah An-Nisaa Verse 48

إِنَّ اللَّهَ لَا يَغْفِرُ أَن يُشْرَكَ بِهِ وَيَغْفِرُ مَا دُونَ ذَٰلِكَ لِمَن يَشَاءُ ۚ وَمَن يُشْرِكْ بِاللَّهِ فَقَدِ افْتَرَىٰ إِثْمًا عَظِيمًا

Innal laaha laa yaghfiru ai yushraka bihee wa yaghfiru maa doona zaalika limai yashaaa'; wa mai yushrik billaahi faqadif taraaa isman 'azeemaa

Translation / The Meaning

Indeed, Allah does not forgive association with Him, but He forgives what is less than that for whom He wills. And he who associates others with Allah has certainly fabricated a tremendous sin.
