249 – Chapter: What One Says When Retiring to Bed

Allah, Exalted be He, says: “Indeed, in the creation of the heavens and the earth and in the alternation of night and day are signs for people of understanding—those who remember Allah standing, sitting, and lying on their sides, and who reflect on the creation of the heavens and the earth.” ⦗Āl ʿImrān 3:190–191⦘ and the following verses.
