Ghusul (the ritual bath with the intention of purification from major ritual impurity) is a worship act. One cannot do a worship act in a way or time when we are not commanded to do it. So she cannot do that. She can, however, just take a regular shower without the intention of it being ghusl.
We rely on our generous community to create a lasting impact and ensure the continuous operations of your Masjid as the gathering place, school, and house of worship for Muslims across the Triangle.
Those who spend their wealth in charity day and night, secretly and openly—their reward is with their Lord, and there will be no fear for them, nor will they grieve.”
– The Holy Quran 2:274
