Hadith 32-19

[21] ‘janabah; The state of ceremonial impurity, or ‘janabah, occurs as a result of ejaculation, whether involuntary, as in the case of a wet dream, or deliberate, or as a result of sexual intercourse. To remove it, one has to take a complete bath, washing his head and every part of his body with water. So a shower without soap is sufficient. It is not possible to offer prayers while a person is in a state of ceremonial impurity. Therefore, it is strongly recommended to remove that state by taking a shower or a bath immediately. It is not good to put it off. However, there is nothing sinful in putting it off, unless that leads to missing an obligatory prayer. If one happens to get into this state two or three times a day, it may not be easy for him to take so many showers. Therefore, he should make sure that removing that state is easy before one gets into it. If it happens two or three times, without taking a shower in between, then one shower would remove it all. Suppose a person goes to sleep after he has said the Morning Prayer, and on waking up he discovers that he has had a wet dream. He realizes that he must leave home immediately because he is late for work. That is appropriate, if he knows that he will return before the time for the noon prayer and he will be able to take his shower and say the noon prayer. Similarly, if one has more than one time of intercourse with his wife during the night, he can have one shower for all. He is recommended, however, to have washed himself in between. Involuntary discharge of urine is an illness which can be treated. For the purposes of prayer, however, one should make sure that the urine does not fall on his clothes or his body. [A urinal discharge does not cause ceremonial impurity and needs washing of the affected areas of the body only.] What he should do is to tie a polyethylene bag with a piece of cotton or tissue paper in it. When he wants to make ablutions and pray, he replaces it with a clean one and makes his ablutions. He only needs to make another ablution for every prayer, repeating the same method for cleanliness.
