The word(s) "unaware" appears 18 time(s) in 18 verse(s) in Quran in Mohsin Khan translation.

(11) And (remember) when your Lord brought forth from the Children of Adam, from their loins, their seed (or from Adam's loin his offspring) and made them testify as to themselves (saying): "Am I not your Lord?" They said: "Yes! We testify," lest you should say on the Day of Resurrection: "Verily, we have been unaware of this."

(12) And to Allah belongs the Ghaib (Unseen) of the heavens and the earth, and to Him return all affairs (for decision). So worship Him (O Muhammad صلى الله عليه و سلم) and put your trust in Him. And your Lord is not unaware of what you (people) do.

(13) Consider not that Allah is unaware of that which the Zalimun (polytheists, wrong-doers) do, but He gives them respite up to a Day when the eyes will stare in horror.

(14) And indeed We have created above you seven heavens (one over the other), and We are never unaware of the creation.

(15) And say [(O Muhammad صلى الله عليه وسلم) to these polytheists and pagans.]: "All the praises and thanks be to Allah. He will show you His Ayat (signs, in yourselves, and in the universe or punishments), and you shall recognise them. And your Lord is not unaware of what you do."

(16) And he entered the city at a time of unawareness of its people: and he found there two men fighting, - one of his party (his religion - from the Children of Israel), and the other of his foes. The man of his (own) party asked him for help against his foe, so Musa (Moses) struck him with his fist and killed him. He said: "This is of Shaitan's (Satan) doing: verily, he is a plain misleading enemy."

(17) And who is more astray than one who calls on (invokes) besides Allah, such as will not answer him till the Day of Resurrection, and who are (even) unaware of their calls (invocations) to them?

(18) And He found you unaware (of the Qur'an, its laws, and Prophethood) and guided you?
