(And that those who have been given knowledge) those who were given knowledge of the Qur'an and the Torah, i.e. 'Abdullah Ibn Salam and his followers (may know) Allah's clarifications (that it is the Truth from thy Lord, so that they may believe therein) so that they believe the clarification of Allah (and their hearts may submit humbly unto Him) so that their hearts be sincere and accept the clarification of Allah. (Lo! Allah verily is guiding) Allah protects (those who believe) in Muhammad (pbuh) and in the Qur'an (unto a right path) to an established religion with which Allah is pleased: i.e. Islam.
