Is rinsing (Nadh) sufficient for purifying a garment from madhy (pre-seminal fluid) according to the Hanbalis, even if traces appear after the garment dries or is immersed in water? And do the Hanbalis differentiate between wet and dry madhy in this regard?

The adopted view of the Hanbali school is that it is obligatory to wash the madhy (pre-seminal fluid) from clothes seven times. There is another narration that permits sufficing with sprinkling (nadh), and in this case, the spot becomes pure by sprinkling, and the persistence of its trace does not matter. There is no difference between dry and wet (madhy).
