khilafah >?

The speech of Allah (SWT) to the Prophet (SAW)also applies to the Ummah. To establish the rule of Allah, entails the establishment of the State and the appointment of a Khalifah, who governs according to Islam. It is incumbent upon the Musilms to establish a state and appoint a leader who applies Islam. The appointment of such a Khalifahis obtained through the Bay'aa.
It has been reported on the autority of Nafi that Abdullah ibn Umar said: I heard the Messenger of Allah (may peace be upon him) say:

"One who dies without having bound himself by an oath of allegiance (to an Amir) will die the death of one belonging to the days of Jahiliyyah." (Muslim)

It has been Narrated on the authority of Abdullah b Amir b al-As that he heard the Prophet (SAW) say:

"He who swears allegiance to a Khalifah should give him the pledge of his hand and the sincerity of his heart (i.e. submit to him both outwardly as well as inwardly). He should obey him to the best of his capacity. If another man comes forward (as claim ant to Khalifah) disputing his authority, they (the Muslims) should behead the latter." (Muslim)

In accordance with Islam, it is the duty of the Muslims world wide to elect a Khalifah. Such an appointment is seen as a duty (fard) similar to all other duties within Islam. The duty is seen as inevitable, and any divergence from the path is considered a grave sin, and therefore any neglect of this duty will be punished accordingly. The establishment of a Khilafah is seen as vital, because without it Islam cannot possibly be applied.
Such factors as: the weakness and deterioration of the Muslim world; the collapse of the Khilafah; the application of Kufr systems in Muslim countries; the removal of Islam from life; the control of Kufr over the Muslim land; the division of the state int o weak countries ruled by agents of the unbelievers; the establishment of Israel plunging itself like a sword into our heart; and the submissive attitude of the Muslims towards Israel; has led the sincere and conscious sons of the great Ummah to think abo ut this terrible situation; to analyse and study the reasons for such a development; to study the various movemts (Islamic and Nationalistic) which were formed in order to save the Muslim world, and the reasons why they failed; to study the large influent ial movents throughout history and the reasons for their success; and to study Islam in depth by referring to the Qur'an, the Sunnah, Ijtihad (exertion on the text) of the Muslim scholars, and the example of how the Prophet (SAW) established the Islamic State.
