days of Ramadan.
This night commemorates the day on which the angel Gabriel brought the entire Quran (holy book of Islam) to earth, as well as the occasion where Muhammad received the first Sura (or chapter) of the Quran in the year 610.
According to the Quran, prayers performed on this night are worth a thousand months of prayer during any other time. This is why many Muslims pray all night on this night.
They may also recite the Quran or have it recited all night.
