‘Amr bin Shu’aib narrated that his father said: “Mu’âwiyah stood up to deliver a sermon and said:‘Where are your scholars? Where are your scholars? For I heard the Messenger of Allah ﷺ say: The Hour will not begin until a group of my Ummah will prevail over the people, and they will not care who lets them down and who supports them’.” (Sahih)
