تَسْمَعُونَ

Appears 2 times in the Quran. (Root: سمع)
  1. O you who believe! obey Allah and His Messenger and do not turn back from Him while you hear.

  2. Say: Tell me, if Allah were to make the night to continue incessantly on you till the day of resurrection, who is the god besides Allah that could bring you light? Do you not then hear?
