Is it necessary to sprinkle water on trousers when pre-seminal fluid (madhiy) is discharged—even if there is no visible trace of it on them—and is it permissible to adopt the view of sprinkling instead of washing for ease and to remove hardship, and what is the method of sprinkling?

Purifying madhi (pre-seminal fluid) from clothing is done by nadh (sprinkling water), which means splashing water on the affected area without the need for scrubbing or squeezing. Sprinkling it once is sufficient if the water reaches the spot touched by the madhi. As for the outer garment, it does not need to be sprinkled unless one is certain that the impurity has reached it.
