Surely, Allah does not forgive that a partner is ascribed to Him, and He forgives anything short of that for whomsoever He wills. Whoever ascribes a partner to Allah commits a terrible sin.
— Mufti Taqi Usmani
God does not forgive the joining of partners with Him: anything less than that He forgives to whoever He will, but anyone who joins partners with God has concocted a tremendous sin.
— Abdul Haleem
Lo! Allah forgiveth not that a partner should be ascribed unto Him. He forgiveth (all) save that to whom He will. Whoso ascribeth partners to Allah, he hath indeed invented a tremendous sin.
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.
— Yusuf Ali
Surely Allah does not forgive that a partner be ascribed to Him,1 although He forgives any other sins for whomever He wills.2 He who associates anyone with Allah in His divinity has indeed forged a mighty lie and committed an awesome sin.
