Sayyiduna Umar (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "A group of my Ummah will always remain upon the truth, until the Hour is established."
Al-Tabarani recorded it in al-Mu'jam al-Saghir and al-Mu'jam al-Kabir; the narrators of al-Kabir are the narrators of the Sahih.
