In Islam there is no Sabbath
A day is not set apart for worship, as in Judaism and Christianity.
One day of prayer with no business and six days of business with no
prayer is not the Muslim’s rule of life. Prayer is made a part
of the everyday affairs of man. There is a prayer in the morning before
sunrise when a man rises from his bed; another just after midday; a
third in the afternoon; a fourth at sunset; and a fifth before going
to bed. Prayer is thus the first daily work of a Muslim; and it is also
his last work of the day, and between these two there are other prayers
during hours of business or recreation. Thus Islam requires that in
all the varying conditions through which man has to pass, his spirit
should be in touch with the Divine Spirit. Even when busiest, he should
still be able to disengage himself from all worldly occupations for
a short space and resort to prayer. The object in view in this arrangement
is clear, that man should feel the Divine presence under all conditions,
so that while he is doing his work, God should still be nearest to his
heart. It would readily be seen how immensely such arrangement must
enhance the value of prayer as a moral force in the transaction of everyday
affairs.
