Then he reinforced his argument by quoting the words of Allah the Exalted: “Indeed, in the creation of the heavens and the earth and in the alternation of night and day are signs for people of insight—those who remember Allah while standing, sitting, and lying on their sides” (Āl ʿImrān 3:190-191).

Regarding “the creation of the heavens and the earth,” that is, in the very substance of the heavens and the earth and in the marvels they contain among Allah’s creatures, there are signs for people of discernment—those endowed with reason who grasp the wisdom and mysteries embedded in Allah’s signs. The sky is vast and elevated, and the earth is spread out and made subservient to humanity; within it lie oceans, rivers, trees, mountains, and countless other manifestations that point unmistakably to their Creator, Glorified and Exalted.

As for “the alternation of night and day,” their variation in length and brevity, heat and cold, ease and hardship, security and fear, poverty and prosperity, and the like likewise holds tremendous signs. When a person studies history and observes the cycling of night and day and their differences, he witnesses wondrous proofs of Allah that only increase his faith.

The phrase “those who remember Allah while standing, sitting, and lying on their sides” is the decisive evidence: they remember Allah in every circumstance—standing, sitting, and reclining—at all times.

He also cited the ḥadīth of ʿĀʾishah (may Allah be pleased with her): “The Prophet ﷺ would remember Allah at all times,” meaning at every moment—whether standing, sitting, or lying down. The Prophet ﷺ even encouraged a person to remember Allah when approaching his spouse, saying, “If, when one of you goes to his family, he says, ‘In the name of Allah. O Allah, keep Satan away from us and keep Satan away from what You grant us,’ then, should a child be decreed between them, Satan will never harm him.”
