The ruling on tayammum (dry ablution with clean earth) for one who is unable to perform wudu' (the ablution for prayer) and has no one to assist him

Question:
I am unable to perform wudu' (the ablution for prayer) by myself, and I have no one to help me. Should I perform tayammum (dry ablution with clean earth), given that the hospital cleans the walls, floor, and bedding daily? How should I perform tayammum (dry ablution with clean earth) in the situation I have described?

Answer:
If the patient has no one to perform wudu' (the ablution for prayer) for him and is unable to perform it himself, he should perform tayammum (dry ablution with clean earth). We wrote to His Excellency the Minister of Health last year and the year before that, requesting that soil be placed under the beds of patients so that they can perform tayammum (dry ablution with clean earth) if they are unable to perform wudu' (the ablution for prayer). The response was that he had issued a directive to hospitals to provide what is needed for patients to perform tayammum (dry ablution with clean earth) in the hospitals. This is a valid approach, for if a person has no access to water and no one to perform wudu' (the ablution for prayer) for him, or is unable to perform wudu' (the ablution for prayer) himself, he should perform tayammum (dry ablution with clean earth) using clean soil placed in a container under the bed, or in any vessel. The patient performs tayammum (dry ablution with clean earth) from it, and this suffices in place of wudu' (the ablution for prayer).
It is not permissible to leave the patient in this state. He must be provided with either water or something with which to perform tayammum (dry ablution with clean earth). If the bedding is clean and the walls are clean with no dust, it is necessary to provide something containing dust, such as soil in a tray or in a bag, to be used for tayammum (dry ablution with clean earth) when needed. Whenever the need arises, he strikes the soil on the bag, or on the mat containing the soil, or on the tray containing the soil, with his clean hands, lightly, and then performs tayammum (dry ablution with clean earth) for the face and hands. This applies to both men and women, and it suffices in place of water if one is unable to use water.
As for the back passage and the front passage, this is sufficient with tissues. He uses the tissues, or the nurse or nursemaid uses them, if the man is unable to do so himself, and likewise if the woman is unable. He wipes the back passage and the private parts with tissues three times or more. It is necessary to wipe three times or more until the area is purified, and this suffices in place of water. If the patient wipes his back passage and front passage with clean, pure, rough tissues until he removes the impurity, and the woman does the same regarding the traces of urine and feces, three times or more, the Prophet (peace and blessings be upon him) forbade performing istinja' (cleaning oneself after relieving oneself) with less than three times. Three times or more, whether using stones, rocks, or tissues, is how a person performs istinja' (cleaning oneself after relieving oneself). Tissues are sufficient if they are clean, pure, and rough, for performing istinja' (cleaning oneself after relieving oneself) from urine and feces three times or more until the area is purified. If three times suffice, praise be to Allah; otherwise, he adds a fourth and fifth time until he is certain.
