the Messenger of Allah said: “When one of you leaves his bed then returns to it, then let him brush it off with the edge of his Izar three times, for indeed, he does not know what succeeded him upon it after him. When he lies down, let him say: ‘In Your Name, my Lord, I lay my side down, and in Your Name I raise it. And if You take my soul, then have mercy upon it, and if You release it, then protect it with that which You protect Your righteous worshippers (Bismika Rabbi Wada’tu Janbi Wa Bika Arfa’uhu, Fa’in Amsakta Nafsi Farhamha Wa In Arsaltaha Fahfazha Bima Tahfazu Bihi Ibadakas-Salihin)’ And when he awakens, let him say: All praise is due to Allah, Who healed me in my body, and returned to me my soul, and permitted me to remember Him (Al-Hamdulillah Alladhi Afani Fi Jasadi Wa Radda Alayya Ruhi Wa Adhina Li Bidhikrih).’”

Every night, when the Prophet would go to his bed, he would join his hands, then blow in them, as he recited in them: “Say: He is Allah, the One.” And “Say: I seek refuge in the Lord of Al-Falaq” and “Say: I seek refuge in the Lord of mankind.” Then he would wipe as much as he was able to off his body with them, beginning with them first of his head and face, and the front of his body. He would do this three times.
