Delaying a ghusl
Question: Until which time is it permissible to delay the ghusl for a person who becomes junub [a person who has to make a ghusl] after performing the night prayer?
ANSWER
Though it is permissible for a person becoming junub after performing the night prayer to delay the ghusl until the morning prayer, it is certainly much better to perform a ghusl immediately. Hadrat Imâm-i Ghazâlî states that if one who has become junub spends a prayer’s time without performing a ghusl one will be made put on a shirt of fire. If anyone, whether practises the daily namâzes [ritual prayers] or not, spends a prayer’s time junub, one will be tormented bitterly. For example, if one, since becoming junub after the early afternoon adhân [call to prayer], has not performed the early afternoon namâz yet, performing a ghusl becomes fard when the remaining time until the late afternoon prayer is sufficient for only the performance of the early afternoon prayer. There are uncountable blessings for those who do a fard, and those who do not perform a fard commit a grave sin.

It is declared in hadîth-i sharîfs:

(When you become impure, hasten to perform a ghusl ablution! For, the angels of kirâman kâtibîn get offended with the person who goes about while junub.) [Hujjat-ul-Islâm]

(Angels of compassion do not enter a house wherein there is a picture, a dog, or a junub.) [Nasâî]

(Angels of compassion do not approach a person who is drunk or junub.) [Bazzâr]

(A person who gets up in order to perform a ghusl ablution will be given as many blessings as the hairs on his body [which means very many], and that many of his sins will be forgiven. His grade in Paradise will be increased. The blessings which he will be given on account of his ghusl are more beneficial than anything in the world. Allahu ta’âlâ will declare to the angels: “Look at this slave of Mine! Without showing any reluctance, he thinks of My command and gets up at night and performs a ghusl from janâbat [the state of being junub]. Bear witness that I have forgiven the sins of this slave of Mine.”) [Gunya]

Giving up the performance of the ghusl
Question: Does one become a renegade if one gives up the performance of a ghusl?
ANSWER
Though one who gives up the performance of a gusl ablution does not become a renegade, one will have committed a grave sin. One who goes about without a ghusl cannot perform namâz [ritual prayer]. Not to perform namâzes is one of the grave sins which leads a person to kufr [disbelief]. It becomes very easy for such a person to lose the îmân [belief]. For this reason, the ghusl must not be delayed! It is stated in a hadîth-i sharîf:
(Allahu ta’âlâ declares: Those who continue to perform these three things are my real friends. On the other hand, those who omit them are my real enemies. These three things are namâz, fasting and ghusl from janâbat.) [Bayhakî]

Would there remain anything like abundance or peace in a house whose owner Allahu ta’âlâ declares to be His enemy and from whose owner angels of compassion stay away?

Youngsters and ghusl
Question: When I get up having had a nocturnal emission, I need to perform a ghusl. In order not to be late for school, is it possible to perform the ghusl after school, even if some prayer times may expire?
ANSWER
A person can make a ghusl in two minutes. It is harâm [prohibited] to spend a prayer’s time junub. Not to perform namâzes is also harâm. It is a rather graver sin to commit a double harâm. One can perform a ghusl even in the school’s restroom.

Going about as a junub
Question: My parents prevent me from performing the ghusl so often, so I go about as a junub. Is a person who dies as a junub a disbeliever?
ANSWER
Even if going about as a junub is a grave sin, one who sins for going about as a junub cannot be called a disbeliever. Not to perform namâzes is a grave sin. A person who is junub cannot perfom namâz. You should explain them in a proper manner that you have to make a ghusl.
