pray, read the Qur'an, and light fireworks.
Sunni Muslims regard the holiday exclusively as a night that determines one's fate for the upcoming year. Sunni's believe that every individual's destiny is recorded on a corresponding leaf on the Tree of Life. When Allah shakes this tree, the next year's course of events is fixed for each person.
Shi'ites believe in these destiny traditions, and also celebrate the birthday of the twelfth imam, a figure in the Shi'ite faith who is expected to redeem the world upon his second coming.
