Asslamu Alikum brothers and sisters,
This is a very good topic, it is true that Khalifa State is the only true political system for Muslims of the world prescribed by none other then all mighty ruler of hevens and the earth and what ever is in between them, Allah (SWT). Followings is the proof of the above statment:
Khilafah/Ummah according To Holy Quran (Allah’s (SWT) order to World Muslims for all the time:
Mankind was one single nation, and Allah sent messengers with glad tidings and warnings and with them he sent the Book in truth, to judge between People in matters wherein they differed, but the people of the book, after the clear signs came to them, did not differ among themselves, except through selfish contumacy, Allah by his grace guided the believers to the truth, concerning that wherein they differed. For Allah guides whom He will to a path that is straight. 2:213 Verily, this Brotherhood/Ummah/Khilafah/State/Nation Of yours is a single Brotherhood/Ummah/Khilafah/Nation/State And I am your Lord And Cherisher: therefore Serve Me (and no other).21: 92 & 23: 52 The Believers are but A single Brotherhood/Khilafah/One State and only one State(no illegal client/NationStates): So make peace and Reconciliation between your Two (contending) brothers(all around 55 present illegal States); And fear Allah, that ye May receive Mercy 49: 10 And hold fast, all together (under one Ummah i.e. Khilafah), by the rope which Allah (stretches out for you), and be not divided among yourselves (like illegal client/Nation States)and remember with gratitude Allah's favor on you for ye were enemies and He joined your hearts in love, so that by his grace Ye became brethren and ye were on the brink of the pit of fire, and He saved you from it. Thus doth Allah make his signs clear to you, that ye may be guided. 3:103 But not like those who are divided amongst themselves (Like Iraq-Kuwait, Saudi,Yemen,Egypt,Turkey, Pakistan etc.) and fall into deputations after receiving clear signs: for them is a dreadful penalty,3:105 (So fear Allah (SWT) and all sub-contractors of illegal client State must handover their illegal present power to elected Khalifah)
Muslim Nations must hand over their present power to elected Khalifah. And as such the 55-nation Organization of Islamic Conference (OIC) must work for the re-establishment of Khilafah/Caliphate immediately.
If there can be European Union under one currency EURO then why we can not re-establish Khilafah?
The Islamic Khilafah/Caliphate survived for long 1300 years until last two Crusades of the European Wars (world wars).
And during that long 1300 years no non-Muslims community under Islamic Khilafah were cleansed in Spain or Eastern Europe, India or anywhere in this World. Where as all original inhabitants in America, Australia and many part of this world were completely cleansed. There is no existence of those original inhabitants in those land, no locality in any big city or even any city.
Thus it is an irony that the illegal immigrants of Australia are taking leading part on East Timor against largest Islamic country i.e. Indonesia. If Indonesia asks Australia Government that Australia belongs to Indonesia and thus illegal Immigrants in Australia must leave that land and go back to their original country i.e. Britain; then what will be reply of those illegal immigrants in Australia. Australia belongs to original people of Australia and its neighbors like Indonesia, India and other neighboring countries and not to the present illegal Immigrants from far away country like Britain.
Only for 800,000 people of East Timor, that land must be separated from Indonesia though people of East Timor, West Timor and other part of Indonesia are the same people, where as though millions of people of Central Asia and Afghanistan were killed by the Russians during last 100 years; yet those people of Chechnya, Dagestan, Afgachia have no right to seek Independence from terrorist country like Russia which displaced and killed millions of Muslims; Muslims man and women of Turkey have no right to demand their religion freedom and lastly 1.5 billion World Muslims have no right to demand their Islamic State of Khilafah/Caliphate, destroyed through International and State Terrorism during last European Wars. Thus 1.5 billion World Muslims have no right to demand their human right or Islamic Shura to elect/select their only one Ruler i.e. Khalifah/Caliph, as they do not deserve any human right or Islamic Shura.
That is the definition of European Crusaders against Muslims and other people of Asia and Africa. Pakistan or Iraq has no right to have few bombs for their defense though European can stockpiled thousands of such big bomb to keep peace in this World, the illegal Immigrant way as they know that they are not legal immigrants of Palestine/Khilafah, America or Australia. And they must keep those big bombs for their safety and to grab more land and cleanse billions of people of Asia and Africa.
They are guilty conscious and afraid for the crime of their ancestors. Thus this is the process of cleansing, endless cleansing and endless war.
We must stop this endless war and endless cleansing and true International/state Terrorism now and only now.
And it is greatest irony that there is no Muslim in this World a single Muslim who can invite to true Islam under Khilafah/Caliphate. It looks that as if there is no Muslim and as such no protests. So called Muslims became Worshippers of money and anti-Islamic Politics of power. They come to United Nation to deliver some speech drafted or guided by their Masters who made them the illegal rulers of the Islamic land.
From Abu Qabeel who said: We were with 'Abdullaah ibn 'Amr ibn al 'Aas and he was asked which city will be conquered first Constantinople or Rome? So 'Abdullaah called for a sealed trunk and he said: Take out a book from it. Then 'Abdullaah said: Whilst we were with the Messenger of Allaah sallallaahu 'alayhi wa sallam writing, The Messenger of Allaah sallallaahu 'alaihi wa sallam was asked: Which city will be conquered first, Constantinople or Rome? So Allaah's Messenger sallallaahu 'alayhi wa sallam said: "The city of Heracilius will be conquered first " meaning Constantinople.[6] The first conquest mentioned, occurred at the hands of Muhammad al Fattaah al-Uthmaanee as is well known and it occurred more than eight hundred years after the Prophet sallallaahu 'alayhi wa sallam foretold of the conquest. So the second conquest will take place, by the permission of Allaah the Most High and it is certain and you will hear of it after a time. There is also no doubt that the fulfillment of the second conquest necessitates the return of the rightly guided Khilaafah to the Muslim Ummah, which is what he sallallaahu 'alayhi wa sallam foretold with his saying in the hadeeth:
An other hadeeth "Prophethood will remain amongst you for as long as Allaah wishes it to, then Allaah will raise it up when He wishes to raise it up. Then there will be Khilaafah upon the manner of Prophethood and it will remain amongst you for as long as Allaah wishes it to, then Allaah will raise it up when He wishes to raise it up. Then there will be harsh kingship which will remain amongst you for as long as Allaah wishes it to, then Allaah will raise it up when He wishes to raise it up. Then there will be tyrannical kingship and it will remain amongst you for as long as Allaah wishes it to, then Allaah will raise it up when He wishes to raise it up. Then there will be Khilaafah upon the manner of Prophethood. Then he was silent.
From the good tidings of the return of strength to the Muslims, and their having the ability to utilize the earth to attain their goals, and that they have a bright future even in the economic and agricultural spheres, or to say in all spheres of life on the earth is evident from prophet's (PBUH)saying.
May Allah Bless you all
