Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "I am leaving behind among you two things; after them you will never go astray: the Book of Allah and my lineage (that is, my descendants). These two will not separate from each other until they both come to me at the Pond."
Al-Bazzar recorded it. Its chain contains a narrator, Salih bin Musa al-Talhi, who is da'if (weak).
