51وَلَوْ شِئْنَا لَبَعَثْنَا فِى كُلِّ قَرْيَةٍ نَّذِيرًا
52فَلَا تُطِعِ ٱلْكَـٰفِرِينَ وَجَـٰهِدْهُم بِهِۦ جِهَادًا كَبِيرًا
53وَهُوَ ٱلَّذِى مَرَجَ ٱلْبَحْرَيْنِ هَـٰذَا عَذْبٌ فُرَاتٌ وَهَـٰذَا مِلْحٌ أُجَاجٌ وَجَعَلَ بَيْنَهُمَا بَرْزَخًا وَحِجْرًا مَّحْجُورًا
54وَهُوَ ٱلَّذِى خَلَقَ مِنَ ٱلْمَآءِ بَشَرًا فَجَعَلَهُۥ نَسَبًا وَصِهْرًا ۗ وَكَانَ رَبُّكَ قَدِيرًا
[51-54] Had We willed, We would have raised up a separate Warner in each habitation.66 So, O Prophet, do not yield to the disbelievers, but wage a Jihad against them with this Qur'an.67
And it is He, Who has let loose the two seas, one palatable and sweet, the other bitter and salty, and there is a partition between them, which is an insurmountable barrier.68
And it is He, Who created man from water: then from him He caused two kinds of kindred, by blood and by marriage:69 your Lord is All Powerful.
66That is, "If We had willed, We could have sent a separate Prophet to every habitation but We did not do so, because like the sun, Our Last Prophet suffices to enlighten the whole world."
67The Arabic words Jihad-i-Kabir imply three meanings:
(1) To exert one's utmost for the cause of Islam,
(2) To dedicate all one's resources to this cause, and
(3) To tight against the enemies of Islam on all possible fronts with all one's resources in order to raise high the "Word of Allah". This will include jihad with one's tongue, pen, wealth, life and every other available weapon.
68This phenomenon has been perceived in many places in the sea and on the land that sweet water and bitter water has existed side by side. Turkish Admiral Syedi Ali Ra'is, in his book Mir 'at-al-Mamalik, written in the 16th century, has mentioned a place in the Persian Gulf, where springs of sweet waver exist under the bitter waters of the sea, where he could get drinking water for his fleet. The American Oil Company at first obtained water from the same springs in the Persian Gulf, before they dug up wells near Dhahran for supply of drinking water. Near Bahrain also there exist springs of sweet water at the sea bed from which people have been taking water until quite recently. Besides this apparent meaning which gives a rational proof of Allah's being the One and the only Lord of the universe, the verse contains a subtle suggestion as well: When Allah wills, He can raise up a righteous community from among a large wicked society just as He can cause springs of palatable and sweet water to gush out from under the salty waters of the sea.
69Here the miracle of the birth of man from a mere sperm drop and the procreation of his offspring from man and woman have been cited as a proof of Tauhid. Though both man and woman belong to the same genus, they are two species, having important common human characteristics but different physical structures and psychological traits. It is a proof of Tauhid that the All-Powerful Allah has used this "difference" for making the two as complements and not antagonists. ' It is also the design of the All-Powerful Creator that He is creating sons and daughters in the world in due proportion Then the sons marry and create blood relationships, and the daughters are married and become means of forming new relationships. This process goes on widening to produce families, tribes and nations belonging to the same race and bound by the same civilization.
The verse has also a subtle suggestion: The whole of life is being run on the principle of "difference", for example, the difference between the night and the day, the summer and the winter, etc. Therefore, " O Muslims, you should patiently endure the differences you are having with your opponents for these are certain to produce good results."
