An item of information provided in the Qur'an about rain is that it is sent down to Earth in ‘due measure.’ This is mentioned as follows: It is He Who sends down water in due measure from the sky by which We bring a dead land back to life. That is how you too will be raised [from the dead]. (43:11)
This measured quantity in rain has been discovered by modern research. It is estimated that in one second, approximately 16 million 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. Some places get more rain one year while other places receive less, and this is changed every year, but the annual world total does not vary.
Therefore, water continuously circulates in a balanced cycle, according to a ‘measure.’ Life on Earth depends on this water cycle. 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. And Allah Ta’ala Knows Best. Z
