What is difference bitween rasool and paghamber?

In Islamic terminology, "Rasool" (Messenger) and "Nabi" (Prophet) have distinct meanings. A Rasool is a prophet who is chosen by God to deliver a new message or scripture to the people, while a Nabi is a prophet who may guide people based on existing teachings without introducing new revelations. All Rasools are considered Nabies, but not all Nabies are Rasools. Thus, the key difference lies in the role of delivering new divine messages versus continuing the guidance of existing ones.
