{Verily! We have sent it [the Quran] down on the Night of Decree (Laylat Al-Qadr). And what will make you know what the Night of Decree is? The Night of Decree is better than a thousand months. Therein descend the angels and the ruh[Gabriel] by Allah's Permission with all decrees. Peace... until the break of dawn.} (Al-Qadr 97:1-7)
"This means that the descending of the angels increases during this night, due to the vast amount of its blessings. And, the angels descend along with the descent of blessing and mercy, just as they descend during the time when the Quran is recited. They encompass the gatherings in which Allah is remembered and spread their wings for the true seeker of knowledge, showing respect for him."
This night occurs only in Ramadan, since the Quran was revealed in it: {Verily, We have sent it [the Quran] down in the night of al-Qadr.} This means that its revelation from Allah to His prophet, Muhammad, began during that month.
What one does while seeking out Laylatul Qadr will vary from person to person. Praying the Isha prayer, the night prayer, and the Fajr prayer, the prayer at dawn, in congregation is important as is every minute in between. Some will then stand for hours in ritual prayer. Others will read or listen to the Quran being recited. Some will sit with their hands raised to the skies with tears falling from their eyes as their hearts tremble out of devotion. My recommendation would be to approach the night with an understanding that it is yours to gain from so what you put into it will yield you what you get out of it. There are so many different ways to benefit from this night, but making sure you are fully present is the first step in attaining that benefit.
Take a moment to break your mind free of any distraction that causes your heart to be shackled in anxiety or pain. Remove from yourself any feeling of emptiness or remorse that comes from having to put on a face that is not your own to gain acceptance from a society that won't take you as you are. Let your thoughts move away from those who can't look beyond the color of your skin, the texture of your hair, the accent that you speak with, or anything else that makes you beautiful. Don't chase after words that are unfamiliar to you but seek and speak with words that are sincerely your own. Be with those who give you hope and courage, who help you to be bold in your prayer. Forget the judgments and harshness of any who have lead you to believe that you cannot ask of your Creator for whatever your heart wishes. Don't inhibit yourself in anyway. God is Most Generous and Most Merciful, and we all are entitled to benefit from that generosity and mercy. You are going to stand in front of the Creator of the Heavens and the Earth, One who looks for a reason to accept from you, not push you away. Laylatul Qadr is for you to seek and benefit from -- don't let anyone, including yourself, take that away from you
