Unable to perform Ghusl
Question

                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 Allah.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.
