What is the ruling on intentionally expelling drops of urine due to obsessive-compulsive disorder (waswas) or forgetfulness, and should one act upon the opinion that does not necessitate purifying the body and clothes from them?

One must turn away from misgivings and not pay attention to them, for that is the best remedy. Maliki jurists facilitate the matter of drops that exit involuntarily (even once a day), so they do not obligate purifying them. However, whatever a person expels voluntarily must be purified.
