Tonight marks the first night of Qadr, also known as the night of power, or the night of measurement, when prayer and supplication and reciting of the Holy Quran are highly recommended, and the night when destinies are determined. The Holy Quran was also revealed on the blessed night of Qadr.

 Laylat al-Qadr  or Qadr night is an opportunity for purifying one's soul from any impurity or pollution .It's time for praying to God and crying so that one's soul becomes purified and free from the heavy burden of sins .It is the time for regretting  one's  misdeeds .

Morphologically,  the word "Qadr" means measurement and  Muslims believe that on  this night their destinies would be determined .However  another meaning of the word includes the real meaning of existence, the characteristics of each and every creature and how it was created . Or putting it another way, "Qadr" means the limit of creation and the perimeter of creation of every creature and object. 

At this night people stay up and reading Quran and Prying to God above .According  to  Holy Quran the angles and the spirit   descend on this night  by God's permission,  and this night is better than 1000 regular months of the year The  Muslims believe  that during Qadr night, every man's destiny for the  next year is  determined .
