Sayyiduna Abu Hurayrah (may Allah be pleased with him) reports this saying of the Prophet (peace and blessings be upon him): "This matter (the narrator is in doubt; perhaps the words are:) a band of my Ummah will remain upon this matter (that is, the religion), and the opposition of whoever opposes them will not harm them, until the command of Allah comes to them."
Al-Bazzar recorded it; its narrators are the narrators of the Sahih, except Zuhayr bin Muhammad bin Qamir, who is thiqah (trustworthy).
