1- Wiping the face with the hand from the effect of sleeping: An Nawawi and Ibn Hajar recommended this act referring to a Hadith narrated by Imam Muslim " .. then the Prophet (PBUH) woke up and sat wiping his face with his hands"
2- Saying this Du'aa: "Thanks to Allah Who gave us life after death , and all resurrection will be to Him." Narrated by Al Bukhari
3- Using "Sewak" (1): "Whenever the Prophet (PBUH) woke up, even at night; he used the sewak to brush his teeth" (agreed upon)
The wisdom behind that is that the sewak flourishes and activates the body and eliminates bad odors.
