Lo! Soon a Hadīth from me will be conveyed to a man, while he is reclining on his couch, and he says: ‘Between us and you is Allah’s Book

The Prophet (may Allah's peace and blessings be upon him) reports that there will soon come a time in which some type of people will be sitting, with one of them reclining on his couch, and when a Hadīth from the Prophet (may Allah's peace and blessings be upon him) reaches him, he will say: What decides the matters between you and us is the noble Qur’an. It is sufficient for us. What we find therein as lawful, we act upon it, and what we find therein as unlawful, we avoid it.

Then, the Prophet (may Allah's peace and blessings be upon him) pointed out that anything he prohibited or forbade in his Sunnah is the same as what Allah prohibited in His Book, for he only conveys from his Lord.
