It is narrated from Sayyiduna Mu'awiyah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The People of the Book split concerning their Book into seventy-two (72) sects, and this Ummah will split into seventy-three (73) sects," meaning on the basis of desires, "all of them will be in Hell except one, and that is the Jama'ah. And indeed, there will emerge in my Ummah people in whom these desires will run as rabies runs through a dog, and no vein or joint will remain that it has not entered."
