The word(s) "unaware" appears 23 time(s) in 23 verse(s) in Quran in Muhammad Pickthal translation.

(11) Lest ye should say: The Scripture was revealed only to two sects before us, and we in sooth were unaware of what they read;

(12) Then changed We the evil plight for good till they grew affluent and said: Tribulation and distress did touch our fathers. Then We seized them unawares, when they perceived not.

(13) And (remember) when thy Lord brought forth from the Children of Adam, from their reins, their seed, and made them testify of themselves, (saying): Am I not your Lord? They said: Yea, verily. We testify. (That was) lest ye should say at the Day of Resurrection: Lo! of this we were unaware;

(14) They ask thee of the (destined) Hour, when will it come to port. Say: Knowledge thereof is with my Lord only. He alone will manifest it at its proper time. It is heavy in the heavens and the earth. It cometh not to you save unawares. They question thee as if thou couldst be well informed thereof. Say: Knowledge thereof is with Allah only, but most of mankind know not.

(15) Allah sufficeth as a witness between us and you, that we were unaware of your worship.

(16) And Allah's is the Invisible of the heavens and the earth, and unto Him the whole matter will be returned. So worship Him and put thy trust in Him. Lo! thy Lord is not unaware of what ye (mortals) do.

(17) Deem they themselves secure from the coming on them of a pall of Allah's punishment, or the coming of the Hour suddenly while they are unaware?

(18) Deem not that Allah is unaware of what the wicked do. He but giveth them a respite till a day when eyes will stare (in terror),

(19) Nay, but it will come upon them unawares so that it will stupefy them, and they will be unable to repel it, neither will they be reprieved.

(20) And those who disbelieve will not cease to be in doubt thereof until the Hour come upon them unawares, or there come unto them the doom of a disastrous day.
