أَيَّان

Appears 6 times in the Quran. (No Root)
  1. They ask you about the hour, when will be its taking place? Say: The knowledge of it is only with my Lord; none but He shall manifest it at its time; it will be momentous in the heavens and the earth; it will not come on you but of a sudden. They ask you as if you were solicitous about it. Say: Its knowledge is only with Allah, but most people do not know.

  2. Dead (are they), not living, and they know not when they shall be raised.

  3. Say: No one in the heavens and the earth knows the unseen but Allah; and they do not know when they shall be raised.

  4. They ask: When is the day of judgment?

  5. He asks: When is the day of resurrection?

  6. They ask you about the hour, when it will come.
