Please teach me a supplication that I may recite when I go to sleep." The Prophet (peace and blessings be upon him) said: "When you lie down on your bed, recite Surah Al-Kafiroon: 'Say: O disbelievers!' Then, after finishing it, go to sleep, for it is a declaration of freedom from shirk (associating partners with Allah)."

Then all his sins are forgiven, even if his sins fill the earth.

You are the First; there was nothing before You. And You are the Last; there will be nothing after You. And You are the Most High; there is nothing above You. And You are the Most Near; there is nothing nearer than You. Remove debt from me and enrich me from poverty.
