تَعْلَمَ

Appears 2 times in the Quran. (Root: علم)
  1. Allah pardon you! Why did you give them leave until those who spoke the truth had become manifest to you and you had known the liars?

  2. So We gave him back to his mother that her eye might be refreshed, and that she might no grieve, and that she might know that the promise of Allah is true, but most of them do not know.
