Has the time for the 'aqiqah passed if twenty-one days have elapsed?

Question:
He says: Honorable Shaykh, may Allah grant you success. Some people say that if twenty-one days have passed, one does not perform the 'aqiqah for the newborn, because it is an act of worship whose time has passed.

Answer:
Its time has not passed, my brother! Its time has not passed, but the days become equal. If twenty-one days have passed, the days become equal, otherwise its time has not passed.
