Da'if Ahadith

“When the son of Adam goes to sleep, the (appointed) angel says to Satan, ‘Show me your record.’ Satan gives him his record, then the angel erases ten evil deeds from Satan’s record for every good deed he finds in (the person’s) record, and writes ten good deeds in their place. Therefore, when any of you is about to sleep, let him say ‘Allahu Akbar’ thirty-three times, ‘Alhamdulillah’ thirty-four times, and ‘Subhanallah’ thirty-three times; these supplications will total one hundred.”
