It was narrated from ‘Awf bin Malik that the Messenger of Allah(ﷺ) said: “The Jews split into seventy-one sects, one of which will be in Paradise and seventy in Hell. The Christians split into seventy-two sects, seventy-one of which will be in Hell and one in Paradise. I swear by the One Whose Hand is the soul of Muhammad, my nation will split into seventy-three sects, one of which will be in Paradise and seventy-two in Hell.” It was said: “O Messenger of Allah, who are they?” He said: “The main body.”
