Immediately upon awakening, rub the face and the eyes with both the palms in order to remove the effects of sleep.
When awakening from sleep, cleanse the mouth with a Miswaak. The use of the Miswaak should be repeated when making Wudhu. Using the Miswaak upon awakening is a separate Sunnah. (Bazlul Majhood)
(After awakening), before immersing the hands into any utensil, wash them thrice thoroughly. (Tirmidhi)
