Is it permissible to assist in performing wudu'?

Question:
Assisting in wudu'?

Answer:
Assisting in wudu' is permissible. The person performing wudu' may have water poured on him by someone else, as al-Mughirah and others did. This is permissible, and it is established from the Prophet (peace and blessings be upon him). If someone other than you pours water from a vessel or otherwise to help you with the wudu' prescribed by Allah, there is nothing wrong with that, as the Chosen One (peace and blessings be upon him) did in the hadith of al-Mughirah, and in the hadiths of Abu Umamah, Abu Dharr, and others.
Q: What if the helper washes some of the limbs?
A: There is nothing wrong with it. If the one being assisted intends it, the helper becomes like a tool. However, it is better for the person performing wudu' to do it himself, as the Prophet (peace and blessings be upon him) did. So the one being assisted does it himself, and the helper pours the water. But if the one being assisted is in a state of illness or the like, then it is sufficient for someone else to wash it, provided he has the intention. So if someone else washes his face, washes his hands, wipes his head, and washes his feet, there is nothing wrong with that; because some people may have their hands incapacitated, or...; so there is no blame on his brother, his wife, or the like assisting him.
Q: Directly assisting someone who does not need it?
A: It is valid. The Prophet (peace and blessings be upon him) did not need it, and Abu Hurayrah assisted him.
Q: Directly washing his limbs?
A: The rule is that there is nothing wrong with it, but it is better for him to do it himself.
