Appears 6 times in the Quran. (Root: علم)
  1. And were it not for Allah's grace upon you and His mercy a party of them had certainly designed to bring you to perdition and they do not bring (aught) to perdition but their own souls, and they shall not harm you in any way, and Allah has revealed to you the Book and the wisdom, and He has taught you what you did not know, and Allah's grace on you is very great.

  2. And when Allah will say: O Isa son of Marium! did you say to men, Take me and my mother for two gods besides Allah he will say: Glory be to Thee, it did not befit me that I should say what I had no right to (say); if I had said it, Thou wouldst indeed have known it; Thou knowest what is in my mind, and I do not know what is in Thy mind, surely Thou art the great Knower of the unseen things.

  3. They said: Certainly you know that we have no claim on your daughters, and most surely you know what we desire.

  4. O our Lord! Surely Thou knowest what we hide and what we make public, and nothing in the earth nor any thing in heaven is hidden from Allah:

  5. The Lord of the heavens and the earth and what is between them, so serve Him and be patient in His service. Do you know any one equal to Him?

  6. So no soul knows what is hidden for them of that which will refresh the eyes; a reward for what they did.
