What should I do if water is available but there is no place to perform ghusl (ritual bath) after major ritual impurity (janabah)?

If a person in a state of ritual impurity (junub) cannot perform ghusl due to the unavailability of a suitable place, they must wait until they find one.

If they fear that the prayer time will expire, they should perform tayammum.

A person in a state of ritual impurity can perform ghusl while covering what is between the navel and the knee with an izar (loincloth) or similar garment, then pour water over the entire body.

This ghusl performed with covering is better, for the Prophet, peace and blessings be upon him, said: "Indeed, Allah, the Almighty and Exalted, is Modest and Concealing; He loves modesty and concealment. So when one of you performs ghusl, let him conceal himself."

If he finds a place where he can perform ghusl in this manner, ghusl becomes obligatory for him, and tayammum is not permissible. If he does not find such a place, tayammum is legislated for him.
