Do you have to clean the blanket and bed sheet every time you have a wet dream?

Assalamu alaykum

Keeping clean and free from impurities is very praiseworthy and is closer to the way of the righteousness as well as being surer for avoiding waswasa (misgivings and doubts about ones acts of worship).

However, one is only obliged to remove impurity from one’s body, clothing and place of prayer, and that is only whilst praying. One is not obliged to remove impurities from wherever one may find it, this would be quite difficult.

And Allah knows best.
