The prayer of the one who is not able to purify himself

Question:

My father is in a hospital and has one of these hospital bags attached to him to relieve himself. He stopped praying because he feels dirty (sometimes he gets dirty with his impurities) what is the ruling of his salat? Will it be valid in these conditions?

Zaynab El-Kateb:

Sheikh Ibn Uthaymeen said that if a person is not able to purify himself, he prays and it is accepted.
