Ghusl

Ghusl (Arabic: غسل‎) is an Arabic term referring to the full-body ritual purification mandatory before the performance of various rituals and prayers, for any adult Muslim after having sexual intercourse, ejaculation or completion of the menstrual cycle, although wudu or just sleep, without either, are the lesser stages of purity that is acceptable.The washing is also recommended but not required (i.e. it is mustahabb) before Jumu'ah and Eid prayers, before entering the ihram in preparation for Hajj, after having lost consciousness and after formally converting.
