The Ruling of Remaining in the State of Janābah until the Time of Fajr
Issue No. 1371- If a junub person does not perform ghusl intentionally until fajr adhān, his fast is void, as an obligatory precaution, and in case he cannot perform ghusl or the time is short, he should perform tayammum. However, if it is not on purpose, his fast is valid. The same ruling applies to a woman who has become pure from ḥayḍ or nifās and does not perform ghusl until fajr adhān. She must act in the same way as a person in the state of janābah.
