Is involuntary urination during sleep, after a wet dream and urinating in the bathroom, considered a trick from Satan, despite diligently reciting Ayatul-Kursi and the pre-sleep remembrances? And what do you advise me to do?

As long as the sister asking the question is committed to her religion and recites Ayat al-Kursi before sleeping, she will find nothing but good, and no devil will approach her during that sleep. For in Sahih al-Bukhari, on the authority of Abu Hurairah, may Allah be pleased with him, that Satan said to him: "When you go to your bed, recite Ayat al-Kursi. A guardian from Allah will remain with you, and no devil will approach you until you wake up." The Prophet, peace and blessings be upon him, said: "He told you the truth, though he is a great liar. That was Satan."

It is recommended to consult doctors, as there may be medication for this condition.
