The Prophet, peace and blessings of Allah be upon him, did not get up after a nap either at night or during the day without using the Siwak, and the Prophet, peace and blessings of Allah be upon him, urged his Umman to use the Siwak all the time, when he said: "Were it not that it would be too hard for my Ummah, I would have commanded them to use the Siwak at the time of every prayer."
