Her grandmother suffers from an inability to maintain her ablution; how should she perform her prayer?

Question:
She has a grandmother who is one hundred years old, and she often complains about not being able to maintain her ablution. So she asks how her prayer should be. May Allah reward you with good.

Answer:
If she does not maintain her purity on a permanent basis, meaning that discharge comes from her on a permanent basis, this is considered a permanent state of ritual impurity. She must perform ablution when she intends to pray; when she wants to pray, she performs ablution and then prays immediately. She owes nothing if something comes out of her, because she cannot control it; she cannot prevent it. This is based on the saying of Allah the Exalted: . And His saying: . And the saying of the Messenger (peace and blessings be upon him): "When I command you to do something, do as much of it as you are able."
As for if this is not on a permanent basis, but rather it comes out at times, or happens to her at times, then it is obligatory for her to renew her ablution, because it is a nullifier of ablution, and it is not on a permanent basis, so it nullifies the ablution. If it happens, she renews her ablution and prays. Yes. May Allah reward you with good.
