Sayyiduna Abu Sabrah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "There is no prayer for the one who has no ablution; there is no ablution for the one who does not mention the name of Allah before it; the one who does not believe in me does not believe in Allah; and the one who does not recognise the right of the Ansar does not believe in me."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator, Yahya bin Abi Yazid bin Abdullah bin Unays, and I have not seen anyone who has given his biography.
