As Salamu Alaikum wa Rahmatullahi wa Barakatuhu Question:Is there a difference between a Messenger and a Prophet?Answer:
Yes, the scholars say that a Prophet is one who receives Revelation from Allah of a law, but he is not commanded to propagate it, only to practice it himself, without being called upon to disseminate it.
A Messenger is one who receives Revelation from Allah of a law and he is called upon to propagate it and to act upon it. Every Messenger is a Prophet, but not every Prophet is a Messenger. The Prophets are more in number than the Messengers and Allah has related the stories of some of the messengers in the Qur'an and other He has not related. Allah the Most High says: “And indeed We have sent Messengers before you (O Muhammad); of some of them We have related to you their story, and some of them We have not related to you their story. And it was not given to any Messenger that he should bring a Sign except by the leave of Allah.” (Surah Ghafir 40:78)
Based on this Verse, it is plain that every Prophet mentioned in the Qur'an is a Messenger.
