Is my prayer valid even though madhy continues to be discharged after ghusl, and I have wrapped my penis with a plastic strip to isolate it from my clothes?

If the discharge of pre-seminal fluid (madhy) stops for a period sufficient for ablution and prayer, then one must wait until it ceases, then perform ablution and prayer. Ablution and prayer performed while madhy is still discharging are not valid. Prayers performed with an invalid ablution must be made up. If the discharge of madhy is continuous and there is a fear of the prayer time expiring, then one must wrap something around the male organ to prevent the madhy from exiting, then perform ablution and prayer.
