Answered by Shaykh Sohail Hanif, SunniPath Academy Teacher
I was wondering whether it is permissible to perform ghusl for exiting the state of janabah by first removing najasa from the body and then jumping in a bath tub filled with water? In other words, does simply entering a tub filled with water and coming out satisfy the requirements for ghusl? I am asking this because if there is little time left to catch a prayer (especially Fajr) then it will be much quicker to do ghusl in this way, rather than to pour water from the shower.
Assalamu Alaykum
Yes it would be permissible to perform a ghusl by merely immersing oneself in a body of water such as a bath tub. One would of course also have to ensure that one cleans one’s nose and rinses one’s mouth. (Maraqi al-Falah)
I would, however, contend the suggestion that this would be quicker than just having a regular shower. By the time one fills up a bath tub with sufficient water one would have nearly completed one’s shower. It would also be safer to have a shower as the slightest amount of filth (najasa) on one’s body would instantly render the water impure and the ghusl invalid.
And Allah knows best.
