[Second: Those who are mistaken :] Then there is the individual who heard (a saying) from the Holy Prophet but did not memorise it as it was, but surmised it. He does not lie wilfully. Now, he carries the saying with him and relates it, acts upon it and claims that: “I heard it from the Messenger of Allāh.” If the Muslims come to know that he has committed a mistake in it, they will not accept it from him, and if he himself knows that he is on the wrong he will give it up.
