My health is not very well and I get
tired very easily. Sometimes I become clear from menses early in the morning at fajr time.
Due to my health, making ghusl at that time would be a hardship for me. What should I do?

Praise be to Allaah, Lord of the Worlds.

First of all, we pray to Allaah to grant you healing and good health.

With regard to your question, if you become pure (i.e., your period
ends) at the time of fajr (the pre-dawn prayer), then it becomes obligatory to
perform ghusl (complete ablution) in order to perform the prayer. If you are not
able to do ghusl because of your illness and inability to do it, then you should do
tayammum (“dry ablution”). This means that you should strike bare earth
once with the palms of your hands, then wipe your face, and the back of each hand with the
palm of the other, then you should pray. And Allaah knows best. May Allaah bless our
Prophet Muhammad.
