Allah's Miracles in the Qur'an

Another item of information provided in the Qur'an about rain is
that it is sent down to Earth in "due measure." This is mentioned in
Surat az-Zukhruf as follows:
It is He Who sends down water in measured amounts from the sky by
which We bring a dead land back to life. That is how you too will be
raised [from the dead]. (Qur'an, 43:11)

This measured quantity in rain has again been discovered by mod-
ern research. It is estimated that in one second, approximately 16 mil-
lion tons of water evaporates from the Earth. This figure amounts to
513 trillion tons of water in one year. This number is equal to the
amount of rain that falls on the Earth in a year. Therefore, water con-
tinuously circulates in a balanced cycle, according to a "measure." Life
on Earth depends on this water cycle. Even if all the available technol-
ogy in the world were to be employed for this purpose, this cycle could
not be reproduced artificially.
Even a minor deviation in this equilibrium would soon give rise to
a major ecological imbalance that would bring about the end of life on
Earth. Yet, it never happens, and rain continues to fall every year in

exactly the same measure, just as revealed in the Qur'an.
The proportion of rain does not merely apply to its quantity, but
also to the speed of the falling raindrops. The speed of raindrops,
regardless of their size, does not exceed a certain limit.
Philipp Lenard, a German physicist who received the Nobel Prize
in physics in 1905, found that the fall speed increased with drop diam-
eter until a size of 4.5 mm (0.18 inch). For larger drops, however, the fall
speed did not increase beyond 8 metres per second (26 ft/sec). 57 He
attributed this to the changes in drop shape caused by the air flow as

the drop size increased. The change in shape thus increased the air
