I want to know what Iqbal said about khilafat and how much is it different from the Hizbul Tahrir ideology(Who also want to establish khilafat ) ?

though i lack in knowledge on this topic.but still in my mind i find a simple reply to this.....iqbal's verse ''nizam-e-padshahi ho k jamhoori tmasha hw,juda ho deen syasat se to reh jati hai chnghaizi''......it means that iqbal surely advocated the ammalgamation of deen(ISLAM) And politics....in islam there's concept of KHILAFAT.....so it becomes that IQBAl advocated KHILAFAT......dunno more about this

as per my knowledge, iqbal has not written much on KHILAFAT, he emphasized more on the prevalent issues. despite my utmost effort i have found a short poem from bang-e-dra which is "DRYUZA-E-KHILAFAT" which means " khilafat ki bheek ya gdae" it goes like:
agar mulk hathon sy jata hai jaye
tu ehkam-e-haq sy na kr be'wafai

nahein tujhko tareekh sy ag'hi kya?
khilafat ki krny lga tu gdai......

khardein na hum jisko apany lahoo sy
musalman ko hai nang(kalank, shrmindgi) wo bashshahi

''مرا از شکستن چناں عار نايد
کہ از ديگراں خواستن موميائي''

(mafhoom ye hai k mery liye marna, dusron sy medicine talab krny sy behtr hai)
which shows that he was not in favour of khilafat. in his poem he HIZR-E-RAAH he writes

"اے کہ نشناسي خفي را از جلي ہشيار باش
اے گرفتار ابوبکر و علي ہشيار باش"

(o! u r unaware of the hidden and the clear, wake up.
o the follower of ABU BAKAR r.a and ALI a.s, wake up")

what i have got form this verse is that, the muslims doesn't know much about islam. so before following the great people first follow their thoughts and teachings. so that one may be able to know what, infact, THEY wanted to tell to the world by their conduct. the following verse verifies these thoughts:

ta khilafat ki bina(base/bunyad) duniya me ho phir ustwar
la kahein sy dhoond kr islaf ka qalb-o-jiagr
he was in favour of khilafat but the one like "khilafat-e-rashida"

Allama Iqbal discussed Khilafat in his book "The Reconstruction of Religious Thought in Islam". Though the whole book is an invaluable treasure but here I am quoting a few thoughts:

Excerpts from The Reconstruction of Religious Thought in Islam:

“Let us now see how the Grand National Assembly has exercised this power of Ijtih«d in regard to the institution of Khil«fat. According to Sunni Law, the appointment of an Imam or Khalâfah is absolutely indispensable. The first question that arises in this connexion is this - Should the Caliphate be vested in a single person? Turkey’s Ijtih«d is that according to the spirit of Islam the Caliphate or Imamate can be vested in a body of persons, or an elected Assembly. The religious doctors of Islam in Egypt and India, as far as I know, have not yet expressed themselves on this point. Personally, I believe the Turkish view is perfectly sound. It is hardly necessary to argue this point. The republican form of government is not only thoroughly consistent with the spirit of Islam, but has also become a necessity in view of the new forces that are set free in the world of Islam.

In order to understand the Turkish view let us seek the guidance of Ibn Khaldën - the first philosophical historian of Islam. Ibn Khaldën, in his famous ‘Prolegomena’, mentions three distinct views of the idea of Universal Caliphate in Islam:

(1) That Universal Imamate is a Divine institution, and is consequently indispensable.
(2) That it is merely a matter of expediency.
(3) That there is no need of such an institution.

The last view was taken by the Khaw«rij. It seems that modern Turkey has shifted from the first to the second view, i.e. to the view of the Mu’tazilah who regarded Universal Imamate as a matter of expediency only. The Turks argue that in our political thinking we must be guided by our past political experience which points unmistakably to the fact that the idea of Universal Imamate has failed in practice. It was a workable idea when the Empire of Islam was intact. Since the break-up of this Empire independent political units have arisen. The idea has ceased to be operative and cannot work as a living factor in the organization of modern Islam. Far from serving any useful purpose it has really stood in the way of a reunion of independent Muslim States. Persia has stood aloof from the Turks in view of her doctrinal differences regarding the Khil«fat; Morocco has always looked askance at them, and Arabia has cherished private ambition. And all these ruptures in Islam for the sake of a mere symbol of a power which departed long ago.

Thus Ibn Khaldën, realizing the hard logic of facts, suggests a view which may be regarded as the first dim vision of an International Islam fairly in sight today. Such is the attitude of the modern Turk, inspired as he is by the realities of experience, and not by the scholastic reasoning of jurists who lived and thought under different conditions of life.

To my mind these arguments, if rightly appreciated, indicate the birth of an International ideal which, though forming the very essence of Islam, has been hitherto over-shadowed or rather displaced by Arabian Imperialism of the earlier centuries of Islam. This new ideal is clearly reflected in the work of the great nationalist poet Êiy« whose songs, inspired by the philosophy of Auguste Comte, have done a great deal in shaping the present thought of Turkey. I reproduce the substance of one of his poems from Professor Fischer’s German translation:

In order to create a really effective political unity of Islam, all Muslim countries must first become independent: and then in their totality they should range themselves under one Caliph. Is such a thing possible at the present moment? If not today, one must wait. In the meantime the Caliph must reduce his own house to order and lay the foundations of a workable modern State.
‘In the International world the weak find no sympathy; power alone deserves respect.’

These lines clearly indicate the trend of modern Islam. For the present every Muslim nation must sink into her own deeper self, temporarily focus her vision on herself alone, until all are strong and powerful to form a living family of republics. A true and living unity, according to the nationalist thinkers, is not so easy as to be achieved by a merely symbolical overlordship. It is truly manifested in a multiplicity of free independent units whose racial rivalries are adjusted and harmonized by the unifying bond of a common spiritual aspiration. It seems to me that God is slowly bringing home to us the truth that Islam is neither Nationalism nor Imperialism but a League of Nations which recognizes artificial boundaries and racial distinctions for facility of reference only, and not for restricting the social horizon of its members.”

For complete understanding and deep insight into the subject, I suggested the interested members to read the aformentioned book of Allama Iqbal. Book is easily available both online and in the market. For full text please go through the following link:

The Reconstruction of Religious Thought in Islam

Now coming to "Hizbu Tarir", what they think about Khilafat:

“The fact that the current existing states in the Islamic world are states of Kufr is evident and does not require explanation, for all of their constitutions do not consider the sins as crimes that entail punishment, and they adopt the systems and the rules of the capitalist democratic system and they effectively implement them in economy, education and all the aspects of life. These constitutions deem the sovereignty to belong to the people, not to Allah (swt), they recognise the international treaties that totally contradict Islam and they do not Islam as a intellectual leadership to the world.”

My Opinion:
Allama Iqbal's views are very comprehensive, inclusive, intellecutal, solutions oriented and meticulous giving you a deep insight into the matter. While, Hizbu Tarir views seem lacking any deep insight, not inclusive and look like empty slogans.
