An-Nisa' (The Women)
Surah 4 · Verse 48
Allah certainly does not forgive associating of partners with Him (polytheism), and He protectively forgives (any sin) other than that, to whom He wills; and one who associates partners with Allah (a polytheist),he indeed fabricates a great sin.
“The sin of polytheism (i.e. associating others with Allah (SWT) as partners or considering them as His equals) will not be forgiven, other sins may be forgiven if Allah (SWT) wills.”
