The ruling on tayammum (dry ablution with clean earth) for a patient who is unable to perform ghusl (the full ritual bath) on his own

Question:
We have a group of brothers from the rehabilitation hospital, the disabled brothers. We ask Allah the Exalted for their healing and well-being. The person in charge of them here asks the following question: He says, “There is a patient who is unable to perform ghusl on his own, but when it is time for prayer, he performs tayammum. What is the ruling in this case? May Allah reward you.”

Answer:
Water is poured over him, he covers his 'awrah (the part of the body that must be covered), and he leaves it so that water is poured over him. It is not permissible to perform tayammum. He wears an izar (loincloth) or trousers, and performs ghusl. One of his brothers pours water over him, or he goes under the shower, under the press, and no one is with him. He moves his clothes, his izar, and everything under the press, and water is poured over him and he washes. This is not an excuse, as long as he has a press under which he can wash. Who said to go to the press and have water poured over him? Or if he has someone to pour water over him, and then he washes his 'awrah, all of this is possible. It is not permissible to perform tayammum except in the case of inability, if he has no one to wash him, and no one to perform wudu' (the ablution for prayer) for him. In that case, he performs tayammum. So fear Allah, and seek forgiveness...
