ابا

Appears 2 times in the Quran. (Root: ابو)
  1. Muhammad is not the father of any of your men, but he is the Messenger of Allah and the Last of the prophets; and Allah is cognizant of all things.

  2. They said: O chief! he has a father, a very old man, therefore retain one of us in his stead; surely we see you to be of the doers of good.
