إِنَّ ٱللَّهَ لَا يَغۡفِرُ أَن يُشۡرَكَ بِهِۦ وَيَغۡفِرُ مَا دُونَ ذَٰلِكَ لِمَن يَشَآءُۚ وَمَن يُشۡرِكۡ بِٱللَّهِ فَقَدِ ٱفۡتَرَىٰٓ إِثۡمًا عَظِيمًا

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

Allah forgiveth not that partners should be set up with Him; but He forgiveth anything else, to whom He pleaseth; to set up partners with Allah is to devise a sin Most heinous indeed.

— An-Nisa' (ٱلنِّسَاء), 4:48
