لا اله الا الله وحده لا شريك له له الملك وله الحمد وهو على كل شىء قدير
The Messenger of Allah (peace and blessings be upon him) said: When Allah returns the soul to a servant (in the morning), and then he recites this supplication «لا اله الا الله وحده لا شريك له له الملك وله الحمد وهو على كل شىء قدير», Allah forgives all his sins, even if they are as much as the foam of the sea.
