Yes, the Prophet Muhammad (peace and blessings be upon him) used miswak.
The use of miswak was a regular practice of the Prophet Muhammad (peace and blessings be upon him). Several hadith (sayings and actions of the Prophet) confirm this.
- Hudhaifa reported: “Whenever the Prophet (peace and blessings be upon him) got up for Tahajjud Prayer he used to clean his mouth (and teeth) with siwak.”
- Another hadith states: “Whenever the Messenger of Allah (peace and blessings be upon him) got up (from sleep), he would rub his teeth with miswak (tooth-stick)..."
These accounts demonstrate that using miswak was a consistent and important part of the Prophet's daily routine, especially before prayer and after waking up. It was considered a sunnah (recommended practice) by him.
