A verse describing the world often closes by naming its audience. The formula is la-āyātin li-qawmin, “surely signs for a people who…”, and the word that finishes it is never the same twice in a row.
Across the 17 verses, five faculties are named, and each verse ends on one of them: those who believe (six times), who reflect (four), who use reason (four), who hear (twice), and who are conscious of God (once, at 10:6).
What the signs are is as varied as who they are for. The alternation of night and day and the ship that runs on the sea (2:164). Water sent down and the growth it brings (6:99). Night made for rest and day made sight-giving (10:67). Spouses, and the love and mercy placed between them (30:21). Sleep by night and day, and the seeking of provision (30:23). Everything in the heavens and the earth, all of it together (45:13).
The list is the 17 verses in which لَآيَاتٍ and لِقَوْمٍ both occur.
How this list was made
Every verse containing both لَآيَاتٍ (la-āyātin) and لِقَوْمٍ (li-qawmin), in muṣḥaf order.
In the creation of the heavens and the earth, and the alternation of night and day, and the ship which runs in the sea with what benefits men, and what God sent down of water from the sky then gave life thereby to the earth after its death, and spread therein every creature, and in the circulation of the winds and the clouds made subject between the heaven and the earth are proofs for people who reason.
And He it is that sends down from the sky water; and We bring forth thereby the growth of all things; and We bring forth from it greenery, bringing forth from it grain heaped up; and from the date-palm, from its spathes, bunches of dates within reach; and gardens of grapevines and olives and pomegranates, similar yet different. Look upon the fruit thereof when it bears fruit and it ripens: in that are proofs for people who believe.
And He it is that spread out the earth, and placed therein firm mountains and rivers; and of every fruit He made therein two kinds; He covers the night with the day; in that are proofs for people who reflect.
And in the earth are tracts adjacent to one another; and gardens of grapevines, and crops, and date-palms with roots shared and independent — watered with one water; and some of them We make exceed in food others; in that are proofs for people who reason.
And He made subject for you the night, and the day, and the sun, and the moon; and the stars are made subject by His command — in that are proofs for people who reason —
Then the response of his people was only that they said: “Kill him, or burn him!” But God delivered him from the fire; in that are proofs for people who believe.
And among His proofs is that He created for you spouses from yourselves that you might be reassured thereby, and made between you love and mercy; in that are proofs for people who reflect.
And among His proofs He shows you the lightning as fear and hope, and sends down water from the sky and gives thereby life to the earth after its death; in that are proofs for people who reason.
God takes the souls at the time of their death, and that which has not died, in its sleep. Then He keeps that for which He has ordained death, and sends down the other to a stated term. In that are proofs for people who reflect.
