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

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.
