Does an unpurified hand after intercourse transmit ritual impurity to the clothes and places it touches?

The transfer of ritual impurity (najāsa) from an impure body to a pure one occurs in three scenarios: If the impurity is wet, everything it touches becomes impure. If the impurity is dry and touches a dry body, the impurity does not transfer. If the impurity is dry and the touched body is wet or moist, there are two opinions on the matter. The more cautious opinion is in line with piety, but if that proves difficult, then the other opinion may be followed. This ruling applies when impurity is present, but semen (manī) is pure.
