who attain success. Indeed, they enjoy a distinction above other people of faith and righteous deeds. As He, the Most High, said:
“Allah will raise those who have believed among you and those who were given knowledge, by degrees.”

The People of the Book have no chains of transmission through which they pass down their reports. The same applies to the innovators within this community, the people of misguidance.

As for this community blessed with mercy and the members of this community safeguarded from error, those among them possessed of knowledge and religious devotion are certain of their affairs. Truth stands apart from falsehood as clearly to them as dawn appears to one who has eyes. Allah has protected them from collectively agreeing upon an error in His religion, whether in matters of reason or transmission.
