‘Ubadah b. al-Samit reported the Messenger of Allah (May peace be upon him) as saying; If anyone is alarmed while asleep and he says when awakes :
there is no god but Allah alone Who has no partner, to whom dominion belongs, to whom praise is due, and who has power over everything (omnipotent). Glory be to Allah, and praise be to Allah, and there is no god but Allah, and then he prays: O my Lord, forgive me. Abu Dawud said : Al-Walid’s version has; and he prays, his prayer will be answered. If he gets up, performs ablution, and prays, his prayer will be accepted.
