have stated that it is permissible to resort to the secret habit if that is
in order to relieve desire that may lead one to fall into the sins of zina
or homosexuality. Similarly it is permissible for the purpose of medical
tests if he is single and needs such tests. And it is permissible to resort
to it if there is the fear of physical harm due to retention of semen.
Perhaps this is what is referred to in the question. In any case, it is not
permissible to go beyond the bounds of necessity, and it is not permissible
to repeat it, and necessity should be measured without exaggerating.
Mansoor al-Bahooti (may Allaah have mercy on him) said:
masturbates by hand for fear of falling into zina or for fear of physical
harm, there is no sin on him if he is not able to get married, not even to a
slave woman, and he cannot afford a slave woman, otherwise it is haraam and
he should be punished by ta’zeer. End quote.
Muntaha al-Iraadaat (3/364) it says:
masturbates, man or woman, when there is no need, it is haraam to do that
and he (or she) should be punished for it by ta’zeer, because it is a sin.
If he does it for fear of zina or homosexuality, there is no sin on him, and
the same applies, even more so, if he does it for fear of physical harm. End
you for giving up this bad habit and urge you to remain steadfast in that,
and if what you did was only because of the pain, then there is no sin on
you in sha Allaah.
