Аль-Фуркан 25:49–56

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.

وَلَقَدْ صَرَّ‌فْنَاهُ بَيْنَهُمْ (And We have distributed it (the water) among them - 25:50). The verse says that We keep rotating the rainfall, that is, it sometimes falls in one locality and sometimes in another. Then sometimes a locality receives in one year more rain and in subsequent years less. Sayyidna ` Abdullah Ibn ` Abbas ؓ says that the presumption of some people that the quantity of rains varies from year to year is not really correct. In fact the aggregate amount of water sent down to the world (at macro-level) is equal every year. However, according to Allah's will, its allocation for different territories may change from year to year. Sometimes the quantity of water is curtailed for a specific habitation as a punishment and warning for it, and sometimes the quantity of rain is increased for a particular population, again as a punishment for their misdeeds. Thus the water that was a blessing in its origin turns into a torment for the people who are ungrateful and disobedient.

Jihad with Qur'an (its propagation) is great Jihad

وَجَاهِدْهُم بِهِ جِهَادًا كَبِيرً‌ا (And strive against them with it (the Qur'an) a great striving - 25:52). This is a Makkan verse when the injunction for Jihad, in the sense of fighting the infidels, had not been revealed. What is ordained in this verse is that you spread the message of Qur'an among the people at large. Propagation of Qur'anic message among people and to make them understand it is great Jihad whether it is by mouth, pen or any other means,

وَهُوَ الَّذِي مَرَ‌جَ الْبَحْرَ‌يْنِ هَٰذَا عَذْبٌ فُرَ‌اتٌ وَهَٰذَا مِلْحٌ أُجَاجٌ وَجَعَلَ بَيْنَهُمَا بَرْ‌زَخًا وَحِجْرً‌ا مَّحْجُورً‌ا ﴿53﴾

And He is the One who joined the two seas - this is sweat, very sweat and this is bitter, very bitter - and made between them a buffer and a barrier, prohibited (to cross) - 25:53.

The word مَرَج (maraja) means to let off or allow to roam freely and hence pasture is called رَج (maraj) that is where animals can graze and roam about. عَذْبٌ ('adhb) is sweet water, while فُراَت means delicious and pleasant; and مِلح (milh) means salty and أُجَاجٌ means bitter.

Allah Ta’ ala in His own Wisdom has created two types of waters. One is enormous in size called oceans and cover up about two third of the global space while the rest of the one third space is made up of land mass on which people live. The water of the oceans and seas is extremely brackish, bitter and of a bad taste. On the other hand the water found on land in different forms is potable, pleasant and tasty. This water is just right for the needs of mankind and animals alike who drink it and use it for cleaning. If the water of the seas and oceans were not brackish, it would have decayed very quickly leaving behind a pungent and foul odor making the life unbearable for humans and animals on land. Moreover, the creatures living in ocean and sea water, and number manifold than those living on land could not have survived because when they die, they perish in the brackish water. If they were to die in sweet water their decomposition would have contaminated the water making the survival of the marine life impossible and its stink would have been unbearable for the life on land. Then the garbage of the land is generally dumped in the sea where it is decomposed (except for a few modern age items which need special treatment). Therefore, brackish water of the oceans and seas is a great blessing of Allah Ta’ ala for all creatures, whether living in the sea or on the land. Without the presence of brackish water mass, there would have been no marine or land life.

In this verse it is elucidated that it is a great blessing and grace of Allah Ta` a1a to have provided two types of waters in accordance with the needs of mankind. Then it is a perfect demonstration of His complete power that when a river of sweet water falls into the sea, the two waters .(the sweet and the brackish) do not mingle immediately where they meet, but for miles they remain separated from each other, despite the fact that there is no physical curtain between them. This is yet another example of His omnipotence.

وَهُوَ الَّذِي خَلَقَ مِنَ الْمَاءِ بَشَرً‌ا فَجَعَلَهُ نَسَبًا وَصِهْرً‌ا (And He is the One who created man from water then made of him kinship of blood and kinship of in-laws. 25:54) نَسَب (nasab, translated above as 'kinship of blood' ) is that relationship which emanates from either parent, and صِهْر (sihr, translated above as 'kinship of in-laws' ) is that kinship which is drawn from the wife's side and is called in - laws. All these relations and bonds are Allah's graces given to mankind for a pleasant and tranquil life. If these relations are taken away from someone's life it will be impossible for him to live by himself.
