Salatul Jumu'ah is a substitute for Zuhr prayer on Fridays; it consists of two genuflexions; it is preceeded by sermon on contemporary topical issues; recitations there in are made aloud; it is characterized by one sitting (Julus), followed by at- Tahiyyat and Taslirn.
According to shiite doctrine, two qunut (raising one hands for supplication during salat) is especially recommended during salatul Jumu'ah. The first Qunut is offered in the 1st rak'at before ruku' and the second is offered in the 2nd rak'at after rising from ruku'.
