Ways of The Prophet (S.A.W)by Sheikh Muhammad Abdul Hai Arifi
The demeanor of the Holy Prophet (Sallallahu Alaihi Wa Sallam)
While going to sleep and getting up he used to go to bed early and got up just after midnight. He would then clean his teeth with a miswak (toothbrush), perform ablution and offer prayers to the extent destined by ALLAH. In this way his whole body and potentialities got rest and ease.
He neither slept nor kept awake more than was needful. As and when he felt the need he would take rest inclined on the right side and remembering ALLAH he fell asleep. At sleeping time, he never ate to this fill. He never slept on the ground nor had a thick bedding. On the other hand he used a leather mattress filled with the bark of date palm. He would rest his head on a pillow and would sometimes place his hand under this cheek and it is best to sleep on the right side. [Zadul Ma’ad]
In sleep he was temperate. He neither slept nor kept himself awake unnecessarily. In other words, the Holy Prophet (Sallallahu Alaihi Wa Sallam) slept as well as kept awake. It was customary for the Holy Prophet (Sallallahu Alaihi Wa Sallam) in offering voluntary prayers and other devotions that he used to go to sleep and then got up for prayers and again went to sleep. In this way he went to sleep and got up many a time. As such anyone who wanted to see him awake could see him like that and anyone who wanted to see himasleep could also see him in that state. [Zad-ul-Ma’ad; Madarij-un- Nubawah]
