He, exalted be He, also said: “We did not create the heavens and the earth and all that lies between them in play; We created them only in truth.” ⦗ad-Dukhān: 38–39⦘

And He said: “We did not create the heavens and the earth and what lies between them except in truth, and the Hour is surely coming.” ⦗al-Ḥijr: 85⦘

After listing His signs at the beginning of Sūrah Yūnus He says: “Allah has not created all this except in truth.” ⦗Yūnus: 5⦘

He says: “Does man imagine that he will be left to himself, unchecked?” ⦗al-Qiyāmah: 36⦘

He says: “Did you suppose that We created you aimlessly and that you would not be returned to Us?” ⦗al-Muʾminūn: 115⦘

He says: “I did not create the jinn and humankind except that they worship Me.” ⦗adh-Dhāriyāt: 56⦘

He says: “Allah is the One Who created seven heavens, and of the earth the like of them; His command descends among them so that you may know that Allah has power over everything and that Allah indeed encompasses all things in knowledge.” ⦗aṭ-Ṭalāq: 12⦘

He says: “Allah has made the Kaʿbah, the Sacred House, a sanctuary for humankind, together with the Sacred Month, the sacrificial animals and the garlands. That is so that you may know that Allah knows whatever is in the heavens and whatever is on the earth, and that Allah is, of all things, All-Knowing.” ⦗al-Māʾidah: 97⦘

From these texts it is evident that the ultimate purpose of both creation and command is that He be remembered and thanked: remembered so that He is not forgotten, and thanked so that He is not denied.

He—glorified be He—remembers whoever remembers Him and is thankful to whoever thanks Him; remembrance of Him leads to His remembering the servant, and gratitude to Him leads to an increase of His favor.

Thus, remembrance belongs to both the heart and the tongue.
