SFQ uses healing sounds but not prayer. Before doing the active exercises you can call upon the master to receive the masters energy. That is not really the same thing as prayer IMO.
Prayer is used in certain sects of daoism but it is not made use of in SFQ to my knowledge. If you want to know about the chinese tradition & taoism I recommend this book -
