'If a person in a state of janabah (ritual impurity due to sexual discharge) immerses themselves in water all at once, that suffices for their ghusl (ritual bath).'. [AL SADUQ] If a person becomes junub (ritually impure) multiple times during a day or night, one ghusl is sufficient unless they become junub again after performing ghusl or experience a wet dream. If they have a wet dream, they should not engage in intercourse until they perform ghusl for the wet dream. There is no issue for a person in a state of janabah to recite the entire Quran, except for the verses of prostration, which are found in Surah Luqman, Surah Ha-Mim As-Sajdah (Surah Fussilat), Surah An-Najm, and Surah Al-‘Alaq A person who is junub or without wudu should not touch the Quran, but it is permissible for them to touch the paper (not the Quranic text) or to have someone else turn its pages, and they may read and mention the names of Allah (swt). A menstruating woman and a person in a state of janabah should not enter the mosque except when passing through it, and they may take something from it, but they should not leave anything in it, as they are able to leave it in other places. If a woman wishes to perform ghusl from janabah but begins menstruating, She should delay the ghusl until her menstruation ends. Then, She should perform one ghusl that covers both janabah and menstruation. There is no issue for a person in a state of janabah to dye their hair, become junub while their hair is dyed, undergo cupping, remember Allah (swt), use depilatory agents, slaughter animals, wear a ring, sleep in a mosque, pass through it, or become junub at the beginning of the night and sleep until the end of it. If a person becomes junub in a place where there is only frozen water and they cannot reach clean soil, they should perform tayammum (dry ablution) and pray, then avoid returning to a place where their faith may be jeopardized. My father, may Allah (swt) have mercy on him, wrote to me: 'There is no issue with dividing the ghusl. Wash your hands, private parts, and head, and delay washing the rest of your body until the time of prayer, at which point you wash your body. However, if you have any hadath (ritual impurity, such as urination or defecation) after washing your head but before washing your body, repeat the ghusl from the beginning. If you begin washing your body before your head, repeat the ghusl for your body after washing your head.'
