Can a junub person (who has to make ghusl) perform fasting? How should one make ghusl when he is junub?

Is it still necessary to gargle well while making ghusl for a person who is fasting?

Dear Brother / Sister,

It is permissible to start fasting or to perform fasting when a person is junub (a person who has to make ghusl); fasting is not invalidated. However, it is not permissible to remain junub so long as to miss a daily prayer; therefore, it is necessary to make ghusl.

It is necessary to wash the mouth while making ghusl. One should wash his mouth without allowing water to go down the throat, that is, without swallowing. It is not necessary to gargle.
