Can someone else help me make wudu?

The Prophet ﷺ accepted help

On a journey, the Companion al-Mughirah poured water for the Prophet ﷺ while he made wudu, and he ﷺ washed his face and arms and wiped his head and khuffs (Sahih al-Bukhari 182). Other Companions did the same on other occasions. So having someone pour water from a jug or bottle is simply a normal kind of help.

Scholars only mention that it's better not to ask for help without need, because doing your own wudu is part of the act of worship. Where there's a need, there's no issue at all.

When you can't wash yourself

For an elderly parent, someone recovering from surgery or a person with a disability, a helper can do more:

• The intention is yours. The person making wudu intends it in their heart; the helper just does the washing.
• Same steps, same order. Wash the face, arms to the elbows, wipe the head, wash the feet, as in normal wudu. See How do I make wudu?
• Sitting or lying down is fine. Use a basin, a jug and towels on a chair or bed.
• Respect privacy. Only uncover what's needed, and use gloves where appropriate.

Islam never asks for more than a person can do:

If even that isn't possible

If water would harm the person, or no one is available to help, they can do tayammum (dry purification with clean earth or a stone surface). A helper can assist with that too. If someone can do neither, scholars say they pray as they are, and Allah accepts it. See How do I do tayammum?

For a missing or artificial limb, there are specific rules. See Can I make wudu with a prosthetic limb?

Caring for parents is worship

Helping a parent or relative with wudu is a deeply rewarded act of service. Many converts find themselves caring for non-Muslim parents too; serving them kindly is part of Islam as well. See Can I put my parents in a care home as a Muslim?
