Rules of the Ghusl of Janabah
Q 166: In case of shortage of time is it permissible for an individual who is in the condition of janabah to offer prayer with tayammum, while his body and clothes are najis or should he clean himself, perform the ghusl, and offer the missed prayer as qada?
A: If there is not sufficient time to purify his body and clothes, or to change the clothes, and it is not possible to offer the prayer while naked due to coldness or the like, he should pray with tayammum instead of performing the ghusl of janabah and with these najis clothes. This prayer is valid, satisfies his obligation, and he is not obliged to repeat it later.
