Allah expresses that the moon follows the sun in
the first of these three Ayahs from completely different sections
of the Quran. That is naturally the case, as we know today after
the establishment of astronomical observation and calculation,
since the moon, although it looks the same size as the sun, is
over 1 million times smaller in volume and 400 times smaller in
diameter. So the law of gravity causes it to follow the sun, just
as the planets and all other objects in the solar system do, which
only build up 0.2% of the mass of the whole solar system, a tiny
fraction in comparison to the sun.
The second of the three Ayahs above expresses the
precision of the courses of the sun and the moon. The fact that
the sun moves at all was not known until the work of Newton had
been accepted. There is a delicate natural balance that has been
set up as a consequence of the complicated gravitational effects.
This a result of the interaction of the various solid (Mercury,
Venus, Earth, Mars, their Moons), gas-type (Saturn, Jupiter, Uranus,
Neptune, Pluto) and plasmatic (Sun) objects of the solar system
during the course of billions of years. Only during the relatively
short period of the crystallisation of the earth and its falling
into the sun, life has become possible on this planet. The "exact
computing" (see Planets & Stars, Speed
of light) of the courses of the sun and the moon make the
measurement of time possible during the day (sun) and the night
(moon and stars) as well as in space-flight.
Finally, the third of the three Ayahs above indicates
the round shape of the earth and the winding or coiling movement
that the shadow of the sun leaves on one side of the earth. It
also covers it in darkness at night while the other side, which
is exposed to the sun, is bright during the day. Tawakir is also
the Arabic expression for coiling a turban around your head. All
the three Ayahs together and also the ones above (see The
Solar System, Course and Orbit)
completely cover course, orbit and motion of the sun, moon and
also the planets. In Sun & Moon
their actual role is described and their difference as well as
eclipses and stages or phases.
The
picture shows NIGHT AND DAY CAUSED BY THE SHADOW AND LIGHT OF
THE SUN. We can associate the following Ayah with it:
"He makes the Night overlap (tawakir) the Day
and the Day overlap the Night:..."
