Surah Al-Furqan, Ayah 49

This is also part of His complete power and supreme authority:

Allah sends the winds as heralds of glad tidings, i.e., they bring the clouds behind them. The winds are of many different types, depending on the purpose for which they are sent. Some of them form the clouds, others carry the clouds or drive them, and others come ahead of the clouds as heralds announcing their coming. Some of them come before that to stir up the earth, and some of them fertilize or "seed" the clouds to make it rain. Allah says:

وَأَنزَلْنَا مِنَ السَّمَآءِ مَآءً طَهُوراً

(and We send down pure water from the sky), meaning, as a means of purifying it. Abu Sa`id said, "It was said: "O Messenger of Allah, can we perform Wudu' with the water of the well of Buda`ah For it is a well in which rubbish and the flesh of dogs are thrown. He said:

وَنُسْقِيَهُ مِمَّا خَلَقْنَا أَنْعَامًا وَأَنَاسِيَّ كَثِيرً‌ا And give drink to the many cattle and humans We have created - 25:49). The word أَنَاسِيَّ is the plural of إنسِیّ and some linguistics have taken it as a plural of إنسَان (both the words mean 'human' ). This verse has described that the rain is a source of irrigation for land, while it serves as a drink for 'many cattle and humans'. The point worth consideration here is why the word 'many' is used which indicates that some human beings do not benefit from it. This question may be answered by saying that the reference here is to the cattle and human beings living in jungles and deserts who directly use the water of rain. As for the urban people, they normally use the water of wells and canals etc.

The phenomenon which in the present age is known as the axial rotation of the earth has been set down here in layman’s language. The earth rotates on its axis once in twenty-four hours, due to which day and night follow upon each other. This is a wonderful miracle of Almighty God’s power. Had there been no axial rotation of the earth, half of it would have been continuously under the blazing sun, while the other half would have been continuously enveloped by night. Thus it would have been extremely difficult to live on the earth. There are many lessons in this system of the earth. Just as the light of day necessarily follows the darkness of night; in the same way untruth will be followed by Truth. Similarly, waking up in the morning after sleeping at night is symbolic of resurrection in the life after death. Likewise, there is a lesson hidden in the system of the rains. Just as the dead earth is revived thanks to the rains, so also does God’s guidance instil faith and fear of God in a heart which otherwise would have become as lifeless as an arid land.
