Islam must be your first allegiance. You are a Muslim first, before any allegiance you give to your family, your tribe, or your country. This does two things: It causes a unity of people across borders which allows the group to grow bigger than any other entity. In other words, the "Nation of Islam" can grow bigger than any country, no matter how large (which gives the group a massive numerical advantage).
The Islam has the unique concept of one Ummah, this Arabic word has very large meanings; it is timeless includes all believers and worshippers of only One God, past, present and future. Ummah is best translated as Brotherhood, "Community", "race", and "nation," and "people" are words which import other ideas and do not quite correspond to "Ummah". "Religion" and "Way of Life" are derived meanings, which could be used in other passages according to context. The people of very different temperaments and virtues, widely different in time, race, color, language, surroundings, history, and work to be performed, but forming the closest brotherhood as being men and women united in the highest service of Allah. They prefigure the final and perfected Brotherhood of Islam. The brotherhood of all followers of Islamic monotheism is one brotherhood:
“Verily, This brotherhood [Ummah] of yours is a single brotherhood, and I am your Lord and Cherisher: Therefore serve me (and no other).”[Qur’an;21:92, ]
Allah's Message was and ever is one; and His all Messengers [Adam, Noah, Abraham Jacob, Moses to Jesus Christ and Muhammad (peace be upon them all)] treated it as one. It is people of narrower views who come later and trade on the earlier names that break up the Message and the Brotherhood into jarring camps and sects.
“But (later generations) cut off their affair (of unity), one from another: (yet) will They all return to us. Whoever works any act of righteousness and has Faith,- His endeavour will not be rejected: we shall record it In His favour. ).”[Qur’an;21:93-94, ]
“But they (mankind) have broken their religion among them into sects, each sect rejoicing in its tenets. So leave them in their error till a time.” [Qur’an;23:53-54]
Hence those calling themselves as Jews and Christians are to be reconciled to be part of this biggest brotherhood:
“The believers are but a single Brotherhood: so make peace and reconciliation between your two (contending) brothers; and fear Allah, that ye may receive mercy.” [Qur’an;49:10]
The revival of the Muslim Brotherhood in some form is the greatest social ideal of Islam. On it was based the Prophet's Sermon at his last pilgrimage, all peaceful endeavors be made to realized this ideal in suitable form. One way to that Muslims should continue to: “Invite (all) to the way of Thy Lord with wisdom and preaching; and argue with them In ways that are best and Most gracious: for Thy knows best, who have strayed from His path, and who receive guidance.” [Qur’an;16:125]
Some people think that Muslim Ummah should be one political unit at global level under the Caliph and they try to resort to all means including violence to achieve it. The UN, EU, Common Wealth and many other organization of cooperation exist, OIC is a loose forum to debate issues faced by Muslims. What ever form of forum or institution is desired to be developed it should not create anarchy, bloodshed or fasad fil ardh but peace. It must be ensured that any such movement should not be based in interpretation of one or two verses but be based upon the over al concepts of Qur’an to ensure that it does not contradict with any verse of Qur’an [no abrogation].
“Unto every one of you have We appointed a [different] law [Shari’a] and way of life [minhaj]. And if God had so willed, He could surely have made you all one single community: but [He willed it otherwise] in order to test you by means of what He has vouchsafed unto, you. Vie, then, with one another in doing good works! Unto God you all must return; and then He will make you truly understand all that on which you were wont to differ.” [Qur’an;]
By origin mankind were a single people or nation [Qur’an;4:1, 2:213]. That being so Allah could have kept all alike, with one language, one kind of disposition, and one set of physical conditions (including climate) to live in. But in His wisdom, He gives diversity to human in these things, not only at any given time, but in different periods and ages. This tests human capacity for Unity (Wahdaniyat) still more, and accentuates the need of Unity and Islam. The term Shari’a is used in the Qur'an to denote a system of law necessary for a community's social and spiritual welfare. The term minhaj, on the other hand, denotes an "open road", usually in an abstract sense: that is, "a way of life". The terms Shari’a and minhaj are more restricted in their meaning than the term din, which comprises not merely the laws relating to a particular religion but also the basic, unchanging spiritual truths which, according to the Qur'an, have been preached by every one of God's apostles, while the particular body of laws (Shari’a) promulgated through them, and the way of life (minhaj) recommended by them, varied in accordance with the exigencies of the time and of each community's cultural development. This "unity in diversity" is frequently stressed in the Qur'an (in the first sentence of 2:148, in 21:92-93, or in ). Because of the universal applicability and textual incorruptibility of its teachings - as well as of the fact that the Prophet Muhammad is "the seal of all prophets", i.e., the last of them (Qur'an;33:40) - the Qur'an represents the culminating point of all revelation and offers the final, perfect way to spiritual fulfillment. Thus now believing and following Prophet Muhammad [pbuh] is obligatory [Qur’an;47:2]. This uniqueness of the Qur'anic message does not, however, preclude adherents of earlier faiths, who by chance could not receive the message of Qur’an, from attaining to God's grace: for - as the Qur'an so often points out - those among them who believe uncompromisingly in the One God and the Day of Judgment (i.e., in individual moral responsibility) and live righteously "need have no fear, and neither shall they grieve".
