Verily, in the creation of the heavens and the earth, and in the succession of night and day, there are indeed signs for all who are endowed with insight [and] who remember God when they stand, and when they sit, and when they lie down to sleep, and [thus] contemplate the creation of the heavens and the earth: “O our Sustainer! Thou hast not created [aught of] this without meaning and purpose. (Qu’ran, 3:-190 -91).
