Is not retaining semen in the body harmful?
Machine translationRead the Arabic original
The questioner : Is it not harmful to retain it?
The Shaykh : Who is the one who is leaking?
The questioner : He says that retaining semen in the body is harmful.
The Shaykh : No, the jurists describe scenarios that may occur with some foolish people, or may not occur at all. Perhaps some people say, "By Allah, I am in heat, and the semen has moved, and I am afraid it will come out and obligate the full ritual bath, so I retain it." Or perhaps his desire cools down; sometimes the semen moves and then the desire cools, and it does not come out. This is the apparent scenario. That is, describing this issue is either as the author stated, where one holds his penis so that the fluid does not come out, or his desire cools down, and when it cools, he is no longer able to ejaculate.
