Lailat-ul-Qadr - The night of Power

In surah AL Qadr Allah (swt) clearly states: "Surely We revealed it
(the Holy Qur'an) on the grand night. And what will make you
comprehend what the grand night. The grand night is better than a
thousand months. The angels and Gabriel descend in it by the
permission of their Lord for every affair, Peace! It is till the break
of the morning." (97:1-5)
