أُمّكُمْ

Appears 6 times in the Quran. (Root: امم)
  1. Forbidden to you are your mothers and your daughters and your sisters and your paternal aunts and your maternal aunts and brothers' daughters and sisters' daughters and your mothers that have suckled you and your foster-sisters and mothers of your wives and your step-daughters who are in your guardianship, (born) of your wives to whom you have gone in, but if you have not gone in to them, there is no blame on you (in marrying them), and the wives of your sons who are of your own loins and that you should have two sisters together, except what has already passed; surely Allah is Forgiving, Merciful.

  2. And Allah has brought you forth from the wombs of your mothers-- you did not know anything-- and He gave you hearing and sight and hearts that you may give thanks.

  3. There is no blame on the blind man, nor is there blame on the lame, nor is there blame on the sick, nor on yourselves that you eat from your houses, or your fathers' houses or your mothers' houses, or your brothers' houses, or your sisters' houses, or your paternal uncles' houses, or your paternal aunts' houses, or your maternal uncles' houses, or your maternal aunts' houses, or what you possess the keys of, or your friends' (houses). It is no sin in you that you eat together or separately. So when you enter houses, greet your people with a salutation from Allah, blessed (and) goodly; thus does Allah make clear to you the communications that you may understand.

  4. Allah has not made for any man two hearts within him; nor has He made your wives whose backs you liken to the backs of your mothers as your mothers, nor has He made those whom you assert to be your sons your real sons; these are the words of your mouths; and Allah speaks the truth and He guides to the way.

  5. He has created you from a single being, then made its mate of the same (kind), and He has made for you eight of the cattle in pairs. He creates you in the wombs of your mothers-- a creation after a creation-- in triple darkness; that is Allah your Lord, His is the kingdom; there is no god but He; whence are you then turned away?

  6. Those who keep aloof from the great sins and the indecencies but the passing idea; surely your Lord is liberal in forgiving. He knows you best when He brings you forth from the earth and when you are embryos in the wombs of your mothers; therefore do not attribute purity to your souls; He knows him best who guards (against evil).
