The night is specific to the exalted Messenger. It has passed. Gabriel has delivered the message (Quran) and he does not descend upon us every year. Moreover there are different Lailatul Qadrs according to the lunar calendar in different parts of the world. Divine forces descend upon those who follow the Quran in letter and spirit. This action and reaction is not confined to any particular night. It is a 24/7 duty.
