Tafsir of Al-An'am 6:75

وكذلك نري إبراهيم ملكوت السماوات واﻻرض

Thus did We show Ibrahim the kingdom of the heavens and the earth..., means, when he contemplated about the creation of the heaven and earth, We showed Ibrahim the proofs of Allah's Oneness over His dominion and His creation, which indicate that there is no god or Lord except Allah. Allah said in other Ayat;

قل انظروا ماذا فى السموت واﻻرض

Say: "Behold all that is in the heavens and the earth.'' (10:101) and,

أفلم يروا إلى ما بين أيديهم وما خلفهم من السماء واﻻرض إن نشٲ نخسف بهم اﻻرض أو نسقط عليهم كسفا من السماء إن فى ذلك ﻻية لكل عبد منيب

See they not what is before them and what is behind them, of the heaven and the earth If We will, We sink the earth with them, or cause a piece of the sky to fall upon them. Verily, in this is a sign for every servant who turns to Allah. (34:9)

وليكون من الموقنين

that he be one of those who have faith with certainty. Allah said next,
