Do they not see the birds suspended in mid-air up in the sky?
Nothing holds them there except Allah. There are certainly signs
in that for people who believe. (Surat an-Nahl, 79) The
illustration shows the main forces acting on a bird during
flight. The tops of birds’ wings are curved, the bottoms flat.
This shape produces lower pressure on the top compared to the
bottom. This difference in air pressure produces a lift force
that enables the bird to rise in the air by beating its wings
upward. (right) (1) The air moving rapidly around the bird’s
wings produces the lift force. (2) The bird bends its wings in
order to obtain greater lift force. The air flowing over the
wings is thus accelerated. (3) If it inclines its wings upward
at a very steep angle, air cannot easily flow to the upper parts
of the wings and the bird loses speed and stalls. Through
Allah’s inspiration, birds make use of the principles of
aerodynamics as they fly. 2 In addition to the aerodynamic
perfection in bird flight, scientists are also
