Supplication when you wake up from sleep

Alhamdu lillaahil-lathee 'ahyaanaa ba'da maa 'amaatanaa wa'ilayhin-nushoor.

اَلْحَمْدُ للهِ الَّذِيْ أَحْيَانَا بَعْدَ مَا أَمَاتَنَا وَإِلَيْهِ النُّشُوْرُ

Meaning:
Praise be to Allah who gave us life after He made us die, and to Him is the resurrection.
(Bukhari 6312, 6314, 6324, 6325, 7395)
