What are all the conditions when ghusl is compulsory?

Is the only time you have to do it is after seminal discharge.

Praise be to Allaah.

The causes that make ghusl a must are:

1. The emission of semen, because the Prophet
(peace and blessings of Allaah be upon
him) said: “What requires water (ghusl) is if you see water (i.e., semen) coming out of you.”
(Reported by Muslim, no. 1/269)

2. Contact between the genitals, because the Prophet
(peace and blessings of Allaah be
upon him) said: “If one part enters the other part (in another report: if one part touches the
other part), then ghusl becomes obligatory.” (Reported by Ahmad and Muslim, no. 526) This ghusl is
obligatory whether or not fluid (semen) is released. “touching” here refers to the entry of the tip
of the penis into the vagina, not mere touching.

3. Menstruation and nifaas (post-natal bleeding), because Allaah says (interpretation of the
meaning): “. . . And when they have purified themselves, then go in unto them as Allaah has
ordained for you. . .” [al-Baqarah 2:222]; and because the Prophet
(peace and
blessings of Allaah be upon him) said to Faatimah bint Hubaysh, may Allaah be pleased with
her: “When your period starts, stop praying, and when your period ends, perform ghusl then
start praying again.” (Reported by al-Bukhari, Fath, 309)

4. Death: the dead – apart from a martyr slain in battle – must be washed (ghusl), because when
his daughter Zaynab died, the Prophet
(peace and blessings of Allaah be upon him)
said: “Wash her with water three or five times, or as many times as you see fit” (Reported by
al-Bukhaari, al-Fath, 1175); and when a man who was in a state of ihraam was killed by his
riding-beast, he said: “Wash him with water and lotus leaves and wrap him in his two garments,
but do not embalm him or cover his head, for he will be raised on the Day of Resurrection
pronouncing the Talbiyah.” (Reported by al-Bukhaari, Fath, 1186)

There are other types of ghusl about which the scholars differed as to whether they are
obligatory, such as performing ghusl on Fridays, or whether a person who becomes Muslim
needs to perform ghusl upon entering the Faith.

There are types of ghusl which are encouraged, such as: ghusl on the two Eids; ghusl after
washing a dead body; ghusl before entering the state of ihraam or entering Makkah; ghusl for a
woman who is suffering from istihaadah (abnormal non-menstrual bleeding) before every
prayer; ghusl after being unconscious; and ghusl after burying a mushrik. (Tamaam al-Minnah by
al-Albaani, p. 120).

And Allaah knows best.
