Did the Prophet (peace be upon him) have a daily litany (wird), and what did he say in it?

The Prophet, peace and blessings be upon him, used to remember Allah at all times, except when relieving himself (urination or defecation) or during intercourse. He would seek Allah's forgiveness more than seventy times a day and recite the Qur'an in all states, unless he was in a state of ritual impurity (janabah). Among the established daily remembrances are: saying "Subhan Allah wa bihamdihi" (Glory be to Allah and praise be to Him) one hundred times, and saying "La ilaha illallah wahdahu la sharika lah, lahul mulku wa lahul hamdu wa huwa ala kulli shayin qadir" (There is no god but Allah alone, without partner. To Him belongs all sovereignty and praise, and He is over all things competent) one hundred times. All goodness lies in following the Prophet, peace and blessings be upon him. To learn about the remembrances reported from him, one can refer to Imam An-Nawawi's book "Kitab al-Adhkar."
