Musannaf Ibn Abi Shaybah 25152 — A man who is frightened by something

Amr bin Shu'ayb narrates from his father, from his grandfather, that the Messenger of Allah (peace and blessings be upon him) said: "When one of you is frightened in his sleep, let him say: 'In the name of Allah. I seek refuge, through the perfect words of Allah Almighty, from His anger, His severe retribution, His wicked servants, the mischief of the devils, and from their coming to me.'"
