There is no blame on those who believe and do deeds of righteousness for what they have eaten (before the prohibition came), provided they guard against (prohibited things in future) and are steadfast in their faith, and do deeds of righteousness and provided they guard against evil (as a duty to themselves); and provided further that they take (God) as a shield, and do good to others (as their duty to their fellow-beings). And Allâh loves the doers of good to others.
