إن الله لا يغفر أن يشرك به ويغفر ما دون ذلك لمن (4:48) بالانجليزي

(4:48) Surely Allah does not forgive that a partner be ascribed to Him, *79 although He forgives any other sins for whomever He wills. *80 He who associates anyone with Allah in His divinity has indeed forged a mighty lie and committed an awesome sin.

Tafseer Abu-al-A'la Maududi

*79). Although the People of the Book claimed to follow the Prophets and the Divine Books they had, in fact, fallen a prey to polytheism.
*80). The purpose of this verse is not to tell man that he may commit any sin as long as he does not associate others with God in His divinity. The object is rather to impress upon those who had begun to regard polytheism as a trivial matter that it constitutes the most serious offence in God's sight, an offence so serious that while other sins may be pardoned this will not. Jewish religious scholars were meticulous about questions of subsidiary importance, and devoted all their time to pondering over legal subtleties which their jurists had painstakingly elaborated by far-fetched deductions. Yet they treated polytheism so lightly that they neither abstained from it themselves nor tried to prevent their people from falling a prey to polytheistic ideas and practices nor found anything objectionable in establishing cordial relations with the polytheists nor in supporting them.
