Rules regarding Janabat

351. A person enters the state of Janabat in two ways:

1. Sexual intercourse

2. Discharge of semen, while sleeping or when awake, little or more, with lust or otherwise, voluntarily or involuntarily.

352. When one cannot ascertain whether the fluid emitted from one's body is semen, urine or something else, it will be treated as semen if it is thrown out with lust and if the body is slackened. If all or some of these signs are not present the fluid will not be treated as semen. In the case of illness, the fluid may not come out with sudden swiftness and the body may not slacken; but if the emission takes place with lust, it will be treated as semen.

353. If a fluid emitted by a healthy person possesses one of the aforesaid three signs and he does not know whether or not it also possessed other signs, and if before the emission he was with wudhu he will content himself with that wudhu. And if he was not with wudhu, it would be sufficient for him to perform wudhu only, and Ghusl would not be necessary.

354. It is Mustahab that a person should urinate after the seminal discharge. If he did not urinate and an emission was seen after Ghusl, which could not been determined as semen or something else, it would be treated as semen.

355. If a person has sexual intercourse with a woman and the male organ enters either of the private parts of the woman up to the point of circumcision or more, both of them enter Janabat, regardless of whether they are adults or minors and whether ejaculation takes place or not.

356. If a person doubts whether or not his penis penetrated up to the point of circumcision, Ghusl will not become obligatory on him.

357. If (God forbid!) a person has sexual intercourse with an animal and ejaculates, Ghusl alone will be sufficient for him, and if he does not ejaculate and he was with wudhu at the time of committing the unnatural act even then Ghusl will be sufficient for him.
However, if he was not with wudhu at that time, the obligatory precaution is that he should do Ghusl and also perform wudhu. And the same orders apply if one commits sodomy.

358. If movement of seminal fluid is felt but not emitted, or if a person doubts whether or not semen has been ejaculated, Ghusl will not be obligatory upon him.

359. A person who is unable to do Ghusl, but can perform tayammum is allowed to have sexual intercourse with his wife even after the time for daily prayers has set in.

360. If a person observes semen on his dress and knows that it is his own, and he has not done Ghusl on that account, he should do Ghusl, and repeat as Qadha all those prayers about which he is certain that he offered them after the discharge of semen.
However, it is not necessary for him to repeat those prayers about which there is a probability that he might have offered them before the discharge of semen.
