Sayyiduna Abdullah bin Sufyan (may Allah be pleased with him) reports this saying of the Prophet (peace and blessings be upon him): "The one who fasts (voluntary fasts) perpetually has not fasted."
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir. Its chain contains a narrator, Muhammad bin Abi Layla, about whom criticism has been made.
