|Is it lawful to sleep on dry semen?
In the name of Allah, Most Compassionate, Most Merciful.
A person may sleep on dry semen; although it is better that a person sleeps where it is clean. However if any substance/particles of the semen can be seen on the clothes or body then they will become unclean and impure. (Durrul Mukhtar, Vol 1, P254)
And Allah knows best.
