One of the beloved pracitce of our Beloved Prohpet Sallallahu Alaihy wasallam is the regular use of Miswak. Hadith states:
Ibn Umar (R) narrates that the Messenger of Allah (Sallallahu Alayhi Wasallam) said:
'Make a regular practice of the Miswaak, for verily, it is healthy for the mouth and it is a Pleasure for the Creator (i.e.
Allah is pleased with the Muslim who uses the Miswaak)'."
Hadhrat Ibn Umar (R) says that many a time Rasulullah used the Miswaak as much as four times in a single night.
"Aisha (R) narrates that Rasulullah (Sallallahu Alayhi Wasallam): said:'These (practices), viz., Miswaak, Witr Salaat and Tahajjud Salaat, are Sunnat for you and Fardh for me'."
So be in constant use of Miswak and take Sunnah Breath.
