What is the guidance for one who delays in the restroom due to doubt about the remaining drops of urine after washing the area?

Question:
Okay, let’s take Abu Muhammad from Jeddah. Go ahead, Abu Muhammad, listen to me. Peace be upon you, and Allah’s mercy and blessings, O Shaykh Abd al-Karim. And upon you be peace, and Allah’s mercy and blessings. By Allah, I wanted to tell you about the prayer. Peace be upon you, O Shaykh. And upon you be peace, and Allah’s mercy. My daughter, Shaykh, I have a son who is sixteen years old, and now, for about four or five months, he has started to delay in the restroom, may Allah honor you. When he performs wudu, he takes a quarter of an hour or half an hour. Sometimes I can say to him, “My son, that’s enough, rely on Allah, sprinkle water on the area of discharge and rely on Him.” He said, “My father, may Allah honor you, the listeners,” and I said, “No, my son, go out and rely on Allah. This is Satan; I want to play with you and so on.” For six or five months, we have been suffering with him, and I do not know, O Shaykh. Sometimes I say, “I rely on Allah and I will attack you with this talk or something.” Okay, the question is clear.

Answer:
In any case, he may have an illness and needs to see a doctor, or this may be a matter of waswas (whispers of Satan). You advised him not to delay, but rather that when he relieves himself, he should clean himself, purify the exit, perform istinja, perform wudu, and pray. This is advice, perhaps Allah will benefit him with it. You warned him about waswas, and you warned him about delaying without a reason, because this causes Satan’s waswas for him and empowers Satan against him. So he should not open a door of waswas for himself and empower Satan against himself. Yes.
