Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
If I fall asleep before completing the adhkar that it is recommended to recite before sleeping should I make them up when I wake up?
You will be rewarded for intending to recite them all even if you fall asleep before completing them. Strictly speaking they are adhkar for a specific time and thus cannot be made up. However, if you do make them up you are guaranteeing yourself the reward for reciting them and teaching your lower self a lesson that it cannot fall asleep before completing them.
