What is the ruling on prayers during which a viscous fluid (madhy) is discharged due to intrusive thoughts and fear of its discharge? And should these prayers be repeated? What is the ruling on leading people in prayer when this fluid is discharged? And is this condition an infatuation, or a struggle against Satan and obsessive-compulsive disorder? What is the advice for this?

One must disregard obsessive thoughts and not pay attention to them. Instead, seek help from a psychiatrist, while relying on Allah and supplicating to Him.

Regarding the fluid discharged after urination, it is likely wady, which nullifies ablution (wudu). If you are certain it was discharged during prayer, then you must exit the prayer and renew your purification. It is not permissible to continue the prayer or delay repeating it until its time has passed. However, if it is merely a doubt about its discharge, do not pay attention to this doubt, and there is no need to investigate it.
