Translation for 4:48

إِنَّ ٱللَّهَ لَا يَغۡفِرُ أَن يُشۡرَكَ بِهِۦ وَيَغۡفِرُ مَا دُونَ ذَٰلِكَ لِمَن يَشَآءُۚ وَمَن يُشۡرِكۡ بِٱللَّهِ فَقَدِ ٱفۡتَرَىٰٓ إِثۡمًا عَظِيمًا ٤٨
Indeed, Allah does not forgive associating others with Him ˹in worship˺,1 but forgives anything else of whoever He wills. And whoever associates others with Allah has indeed committed a grave sin.

 A person will never be forgiven if they die as a disbeliever. But if they repent before their death and mend their ways, then their repentance will be accepted (see 25:68-70).
