The Saved Group

Ahmad ibn Abee 'Aamir Al-Hoozanee related that Mu'aawiyah ibn Abee Sufyaan stood and said, "Indeed the Messenger of Allah (peace and blessings of Allah be upon him) stood among us and said,

“Lo! Indeed those before you from the People of the Book divided into 72 sects, and indeed this religious community (i.e., this nation) will be divided into 73 (sects) - 72 in the Hellfire and one in Paradise, and they are the jamaa'ah.”

[Narrated by Abu Dawud]

In another narration, when they asked the Prophet(peace and blessings of Allah be upon him), about the saved group, he (peace and blessings of Allah be upon him) said,

"That which I and my Companions are upon today."

[Narrated by Mustadrak Al-Haakim]
