Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "A servant cannot reach the reality of faith until he keeps control over his tongue."
Al-Tabarani recorded it in al-Mu'jam al-Saghir and al-Mu'jam al-Awsat; its chain contains Dawud bin Hilal, whom Ibn Abi Hatim mentioned without mentioning any weakness in him. The rest of its narrators are the narrators of the Sahih, except Zuhayr bin Abbad, and a group declared him trustworthy.
