What is the ruling on one who does not perform istinja' (cleaning oneself after relieving oneself) from urine because he has incontinence, so when the time for prayer comes, he only changes his clothes?

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the ruling on one who does not perform istinja' or istijmar (cleaning with a stone) from urine because he has something like incontinence, so when the time for prayer comes, he changes all his clothes that the impurity fell on?

Answer:
It is obligatory to perform istinja' when he wants to pray; it is obligatory to perform istinja' with water, then place something on his penis after istinja' to prevent what comes out of him from leaking, so istinja' is obligatory. But for some of what leaks, he places something on it to prevent what leaks from him and prays. He performs wudu' (the ablution for prayer) and prays according to his condition, and he does not leave off istinja'. Because istinja' or istijmar are conditions, or a condition, for the validity of wudu'; among the conditions for the validity of wudu' is istinja' or istijmar before it. Yes.
