Islam is very concerned about cleanliness/holiness and views it as important as an inseparable part of a series of worship. In the implementation of worship, there is a need for cleanliness/holiness itself. This means that true worship is worship performed by people who have maintained cleanliness and purified themselves. There are still many researchers who see children or people performing ablution carelessly or imperfectly. This time the researcher took the theme of learning the practice of ablution which aims to make the children of TPA Al-Hidayah able to carry out their obligations properly and correctly, so that what we teach them can be useful for the life of the community or the life to come. The research method used is the PAR (Participation Action Research) method, covering learning activities, mentoring, planning, research, development to the implementation of research programs involving the wider community or specific target groups. As for the results of this service program research, children can distinguish between rubbing and washing in ablution.
