Hazrat Ali :“The family of Mohammad – peace be upon him and his progeny – are like the stars in the sky, if a star was to no longer become apparent, another would take its place, it is as if Allah has perfected his blessing for you and showed you what you wished for.”
The sermon is clear that there is no such thing as ghaybah (occultation). This indicates that Hazrat Ali was not aware of the concept that would one day spread and be adopted by Shias all around the world.
