The word(s) "region" appears 6 time(s) in 6 verse(s) in Quran in Saheeh International translation.

(1) And We caused the people who had been oppressed to inherit the eastern regions of the land and the western ones, which We had blessed. And the good word of your Lord was fulfilled for the Children of Israel because of what they had patiently endured. And We destroyed [all] that Pharaoh and his people were producing and what they had been building.

(2) Allah has already given you victory in many regions and [even] on the day of Hunayn, when your great number pleased you, but it did not avail you at all, and the earth was confining for you with its vastness; then you turned back, fleeing.

(3) And if they had been entered upon from all its [surrounding] regions and fitnah had been demanded of them, they would have done it and not hesitated over it except briefly.

(4) You will see the wrongdoers fearful of what they have earned, and it will [certainly] befall them. And those who have believed and done righteous deeds will be in lush regions of the gardens [in Paradise] having whatever they will in the presence of their Lord. That is what is the great bounty.

(5) And mention, [O Muhammad], the brother of 'Aad, when he warned his people in the [region of] al-Ahqaf - and warners had already passed on before him and after him - [saying], "Do not worship except Allah. Indeed, I fear for you the punishment of a terrible day."

(6) O company of jinn and mankind, if you are able to pass beyond the regions of the heavens and the earth, then pass. You will not pass except by authority [from Allah].
