Chapter: Taking refuge with Allah, and the recitation before going to bed

Whenever Allah's Messenger (ﷺ) went to bed, he used to blow on his hands while reciting the Mu'auwidhat ( i.e. Suratal-Falaq 113 and Surat-an-Nas 114) and then pass his hands over his body.

The Prophet (ﷺ) said, "When anyone of you go to bed, he should shake out his bed with the inside of his waist sheet, for he does not know what has come on to it after him, and then he should say: 'Bismika Rabbi Wada`tu Janbi wa bika arfa'uhu, In amsakta nafsi farhamha wa in arsaltaha fahfazha bima tahfazu bihi ibadakas-salihin."
