Possible Reason Why Muslim Ummah is suffering Badly:

  Yet you it is who slay your people and turn a party from among you out of their homes, backing each other up against them unlawfully and exceeding the limits; and if they should come to you, as captives you would ransom them-- while their very turning out was unlawful for you. Do you then believe in a part of the Book and disbelieve in the other? What then is the re ward of such among you as do this but disgrace in the life of this world, and on the day of resurrection they shall be sent back to the most grievous chastisement, and Allah is not at all heedless of what you do. These are they who buy the life of this world for the hereafter, so their chastisement shall not be lightened nor shall they be helped. (Al_Quraan_002.085-086)

(Here Believing means Practicing. Islaam is a Practical Religion and NOT a Verbal Religion. Today vast majority of Muslim Ummah are not Practicing Islaam completely, so it means, they are believing in some parts of the Quraan, while disbelieving in the others.)

Allah has promised for the great bounty, BUT why Muslim Ummah are suffering:

And if the people of the towns had believed and guarded (against evil) we would certainly have opened up for them blessings from the heaven and the earth, but they rejected, so we overtook them for what they had earned. (Al_Quraan_007.096)

Do not hold the Messenger's calling (you) among you to be like your calling one to the other; Allah indeed knows those who steal away from among you, concealing themselves; therefore let those beware who go against his order lest a trial afflict them or there befall them a painful chastisement. (Al_Quraan_024.063)

Behold! You are those who are called upon to spend in Allah's way, but among you are those who are niggardly, and whoever is niggardly is niggardly against his own soul; and Allah is Self-sufficient and you have need (of Him), and if you turn back He will bring in your place another people, then they will not be like you. (Al_Quraan_047.038)

Shall I then seek a judge other than Allah? And He it is Who has revealed to you the Book (which is) made plain; and those whom We have given the Book know that it is revealed by your Lord with truth, therefore you should not be of the disputers. (Al_Quraan_006.114)

Those who don't do Justice according to the Laws of Allah they are unbelievers:

Surely We revealed the Taurat in which was guidance and light; with it the prophets who submitted themselves (to Allah) judged (matters) for those who were Jews, and the masters of Divine knowledge and the doctors, because they were required to guard (part) of the Book of Allah, and they were witnesses thereof; therefore fear not the people and fear Me, and do not take a small price for My communications; and whoever did not judge by what Allah revealed, those are they that are the unbelievers. (Al_Quraan_005.044)

What about those Muslim Rulers, who don't implement the True Islamic Laws, how come they are Muslim? What about those who appoint them by giving vote in a democratic system, although there are others asking their support, so that they may be able to implement the True Islaamic System (Khilafa)? What about those who don't go for vote where there is a democratic system, to elect someone who is promising to implement the True Islaamic System? As an example, suppose 3% who wants Islaamic System, but didn't vote, 49% vote to Non-Islaamic party while 47% vote to Islaamic Party. Then Non-Islaamic Party will be in the power only because of 3% people. Why there are so many divided Islaamic Parties? Suppose that the majority of the people don't want Islaamic System then, would you like to force the people or do Dawah and leave the rest on Allah? A Muslim can never vote to a Non-Islaamic party, while there are Islaamic Parties available. These things are extremely important and need TRUE Justice otherwise the corrupt Rulers will be appointed and will destroy the Nation. You must need to help those who are sincerely & peacefully trying to build the Khilafa (United States of Islaam).

Those who vote for NON-Islaamic Party May be actually Disbelievers:

O ye who believe! Whoso of you becomes a renegade from his religion, (know that in his stead) Allah will bring a people whom He loves and who love Him, humble toward believers, stern toward disbelievers, striving in the way of Allah and fearing not the blame of any blamer. Such is the grace of Allah, which He gives unto whom He will. Allah is All Embracing, All Knowing. [Al_Quraan_005.054]

Remember: There is no Compulsion in the Religion… (Al_Quraan_002.256)

Those who Divide the Religion are NO Longer Muslims:

As for those who Divide their Religion and break up into Sects, thou hast NO part in them in the least: their affair is with Allah. He will in the end tell them the truth of all that they did." [Holy Quraan 6: 159]

Allah wants us to be United Perfectly:

If you DIFFER in anything (Faith, Salaat, Sayaam, Zakaat, etc.) amongst yourself, then REFER to Allah and his Messenger, if you really believe in Allah and in the Last Day. That is better and more suitable for determinations. [Al_Quraan_004.059]

Weather you believe or not, our Foundation (Worshipping Method) is widely divided into several sects. Not only every group, believing on, that they are right, BUT every person practically believe that he is right, and perfect, so he is acting accordingly.

Check your Faith, Kalimah, Salaat, Sayaam, Zakaat, Hajj, etc (Every Act including Worship). Think again, why you are different from other Muslims. First see yourself, may be you are not Correct.

Only No Innovations, No Additions or Subtractions in our Faith, Kalimah, Salaat, Sayaam, Zakaat, Hajj, etc. will bring us to Perfect Unity
