Definition of the Prophet & the Messenger Every
rasool (messenger) is a nabiyy (prophet), but not every nabiy is a
rasool. Nabiyy is one whom Allaah has informed about a previous Divine
law, sending him to warn the people to whom it applies. As for a
rasool, he is one whom Allaah sent with a new law or Sharee'ah,
commanding him to convey it to people.
