{3:191} those who remember Allah standing and sitting and lying on their sides and reflect on the creation of the heavens and the earth: Our Lord! Thou hast not created this in vain! Glory is to Thee; save us then from the chastisement of the fire:

{39:42} … most surely there are signs in this for a people who reflect.

{30: 21} … most surely there are signs in this for a people who reflect.

{45:13} … most surely there are signs in this for a people who reflect.

{13:3} … most surely there are signs in this for a people who reflect.

{2:219} … Thus does Allah make clear to you the communications that you may ponder?
