The third: he does not know whether it is semen or not. If there is some indication by which it may be judged to be semen or pre-seminal fluid, the ruling is based on that indication. If there is no such indication, then the basic presumption is purity and that ghusl is not obligatory. The manner of determining the ruling is as follows: if he remembers having had a wet dream, we deem it to be semen, because when the Messenger of Allah, peace and blessings be upon him, was asked about a woman who sees in her sleep what a man sees in his sleep—must she perform ghusl?—he replied, “Yes, if she sees the fluid.” (1) If he saw nothing in his dream, but had thought about intercourse before going to sleep, we deem it to be pre-seminal fluid, because it may be emitted after thinking about intercourse without one being aware of it. If no such thoughts preceded it, then the scholars have two views:

It was said that he must perform ghusl as a precaution. (2)

And it was said that it is not obligatory (617). Here, two legal presumptions are in conflict.

“And if it moves but does not emerge, he must perform ghusl on its account, ………”

His statement, “And if it moves but does not emerge, he must perform ghusl on its account,” refers to semen; that is, he feels it moving, but it does not emerge. He must then perform ghusl, because the fluid has moved away from its place, and he is therefore deemed to be in a state of janabah (major ritual impurity), for janabah literally denotes distance.

Can it move without emerging?

Yes, this is possible: his desire may subside after it has moved, for some reason, and the semen therefore does not emerge.

They also give another example: that he holds his penis so that the semen does not emerge. Although the jurists cite this as an example, it is very harmful, and the jurists
