ربما تكون ليلة القدر ,,

Laylatul Qadr (the Night of Power) is described in the Quran as, "better than a thousand months" (97:3). Any action done on this night such as reciting the Quran, remembering Allah, etc. is better than acting for one thousand months which do not contain the night of Qadr.

The Prophet said: "Whoever prays during the night of Qadr with faith and hoping for its reward will have all of his previous sins forgiven." (Bukhari and Muslim recorded from Abu Huraira).

لقول النبي صلى الله عليه وسلم ( من قام ليلة القدر إيمانا واحتسابا غفر له ما تقدم من ذنبه ) متفق عليه
