How is it possible to pray in a garment that has been touched by semen, knowing that pre-seminal fluid (madhiy) is impure and is discharged before semen, which means that the garment would have also been touched by madhiy, and therefore must be sprinkled with water?

The emission of pre-seminal fluid (madhy) before seminal fluid (maniy), or the emission of seminal fluid without pre-seminal fluid, is not a necessary sequence; each can be discharged independently. Purification of the body and garment from pre-seminal fluid is not obligatory unless its discharge is confirmed; doubt alone does not necessitate purification.
