(July 31, 2014 at 8:40 am)Muslim Atheism Wrote: Mankind is one nation

The Quran says that mankind are the descendants of Adam.

• And when your Lord
  took from the children of Adam (one nation)
  from their loins
  their descendants (no religion)
  • and made them testify of themselves
    [saying to them], "Am I not your Lord?"
    They said, "Yes, we have testified." (the Covenant)
    [This] - lest you should say on the day of Resurrection
    "Indeed, we were of this unaware"
    (7:172)

. . .
That is the origin of mankind from the Quran , as one nation. . .
and the main theme of the Quran and the test for human beings is to live in peace as one nation;
as children of Adam, regardless of their religions.

• Mankind was one Ummah/Nation (2.213)

. . .
The Quran says Allah gave signs about unity in diversity in all His creations,
gave mankind Books of guidance that corroborates with nature and made them into sects and religions,
so that they can learn about "balance" (wisdom) and strive to be one nation.
So that people can progress and become leaders, the Caliph. . the successor on Earth,
ie. who can accept ALL religions and ALL Gods with open heart, and no "sectarianism".

• And your Lord said to the angels:
  "I am placing a successor on the earth."
  (2.30)
  
  God promises those among you who believe and do good works,
  that He will make them successors on the earth,
  as He made successors of those before them, (real successor, to all)
  and He will enable for them their system
  which He has approved for them,
  and He will substitute security for them in place of fear:
  "That they serve Me, not setting up anything with Me."
  And as for those who reject after that, these are the wicked.
  (24.55)
  
  [We said], "O David, indeed We have made you a successor upon the earth,
  so judge between the people in truth and do not follow [your own] desire, (ie. I am God)
  as it will lead you astray from the way of Allah ."
  Indeed, those who go astray from the way of Allah
  will have a severe punishment for having forgotten the Day of Account.
  38.26

. . .

and that's why Allah makes and divide people into sects, ie. religion etc. . .

• So, the devil caused them to slip from it,
  and he brought them out from what they were in, and We said:
  • "Descend; for you are enemies to one another;
    and on the earth you will have residence and provisions
    until the appointed time."
  Adam then received words from His Lord, so He forgave him;
  He is the Forgiver, the Merciful. We said:
  • "Descend from it all of you,
    so when the guidance comes from Me,
    then whoever follows My guidance,
    they will have nothing to fear,
    nor will they grieve."
  2:37-39

• Say: He has the power
  that He should send on you a chastisement from above you
  or from beneath your feet, or that
  He should throw you into confusion,
  (making you) of different religion (شِيَعًا)
  and make some of you taste the fighting of others
  See how We repeat the communications
  that they may understand (their mission is unity in diversity)
  6.65

• And We have sent down to you the Book with the truth,
  authenticating what is between your hands of the Book
  and superseding it.
  So judge between them by what God has sent down,
  and do not follow their desires
  from what has come to you of the truth.
  
  For each of you We have made laws, and a structure;
  • and if God had willed, He would have made you all one nation,
    but He tests you with what He has given you;
    so strive to do good (unity). To God you will return all of you,
    and He will inform you regarding that in which you dispute.
  5:48

. . .
While people are free to adhere to their religions,
they should comply with the ethics for unity in diversity.
These rules were made for mankind to live in peace and as one nation, regardless of their religions.

• This is because God has sent down the Book with the truth;
  and those who have disputed about the Book
  are in open schism (شِقَاقٍ). (definition of sectarianism)
  2.176

. . .
Those who dispute the practical code of ethics contravene the overall systems of nature, unity in diversity. . .the Contraveners

• And if your Lord had wished
  He could have made all the people one nation
  but they still would have continued to disagree (through sectarianism).
  11:118
  
  And if God had wished, He would have made you one nation,
  but He misguides whom He wishes,
  and He guides whom He wishes.
  And you will be asked about what you used to do.
  16:93
  
  And if God had willed, He could have made them one nation.
  But He admits whom He wills into His mercy.
  And the transgressors will have neither an ally, nor helper.
  42:8

. . .
Therefore, mankind is one nation . .
there should be no sectarianism and people should live in peace as one nation.
This is the main purpose of life, to live as one family.
