Prohibited times of prayer
There are three principal times in which prayer is unlawful:
(1) When the sun is in the course of rising; (2) when the sun is just
in the meridian; and (3) when the sun is in the course of setting. The
prohibition is chiefly due to the fact that a Muslim’s action
must be in opposition to that of the polytheists. The object is the
pluck out idolatory in any shape or form. The sun, when it rises, sets
or in the meridian, is worshipped by many nations. If prayer is offered
at these times, some people may be led to think that Islam also sanctions
the worship of the sun.
