Using the siwak is a confirmed Sunnah (Sunnah mu’akkadah) of the Prophet (blessings and peace of Allah be upon him). He (blessings and peace of Allah be upon him) said: “Were it not that it would be too difficult for my ummah, I would have instructed them to use the siwak at the time of every prayer.” The siwak is cleansing for the mouth and pleasing to the Lord. In this hadith, the Prophet (blessings and peace of Allah be upon him) confirmed the command to use the siwak, as he said: “I have mentioned to you many times the importance of using the siwak”, to emphasize its importance and enjoin it. The siwak is obtained from the roots of the arak tree. The point of telling them this, even though they were already aware of it, is to highlight and emphasize the importance of using the siwak. Even though the siwak is Sunnah at all times, it is even more important in certain situations, including prayer, wudu’ and reading Qur’an. As Jumu‘ah is one of the prayers for which the Muslims are enjoined to adorn themselves and prepare themselves for it by doing ghusl and putting on perfume, and using the siwak is one of the means of cleansing and purifying oneself, it is even more important on Friday..
