According to Qur'ān 4:48, to set up partners with Allah is a great offense which Allah will not forgive

A.

Except the prophet (S.A.W) intercedes

B.

until He has forgiven all other sins

C.

except the offender repents

D.

even if He forgives all other sins

Correct answer is D

English Transliteration:
Innallaaha laa yaaghfiru an yushraaka bihee wa yaagfiru maa doona zaalika li man yasha' wa man yushrik billaahi fa qadiftaraa isman aazeema.

Verily, Allah does not forgive to be associated partners with Him. And forgives what is besides that for whomsoever He wills; and whoever associates anything with Allah, he has indeed slandered with a tremendous sin.
