Iqbal turns to Turkey's Religious Reform Party and its Grand Vizier Saʿīd Ḥalīm Pasha, whose vision of Islam as a universal system distorted by local pre-Islamic accretions provides a more authentically Islamic route to the same reformist conclusions. He then applies this substantive ijtihād to the Caliphate, endorsing the Turkish position that the institution need not be vested in a single person but can legitimately reside in an elected assembly.
Sections 4 and 5 examined the Turkish Nationalist Party's position — the separation of Church and State — and Iqbal's metaphysical critique of it as a Christian import inapplicable to Islam. Section 6 now turns to the second current of Turkish thought: the Religious Reform Party, led by the Grand Vizier Saʿīd Ḥalīm Pasha, which reaches 'practically the same conclusion' as the Nationalists — the freedom of ijtihād to rebuild the Sharīʿah — but through a 'line of thought more in tune with the spirit of Islam.' The section then applies this reformist ijtihād to the most consequential institutional question in modern Islam: the Caliphate.
The section advances through four movements. First, Iqbal presents Saʿīd Ḥalīm Pasha's argument that Islam, as a 'unity of the eternal verities of freedom, equality, and solidarity,' is universal and has no fatherland — just as there is no 'English Mathematics' or 'German Astronomy,' there is no Turkish, Arabian, or Indian Islam. The universality of Islamic principles generates varieties of national cultures, but the principles themselves transcend national boundaries. The Grand Vizier diagnoses the central problem: Islamic moral and social ideals have been 'gradually deislamized' through local pre-Islamic influences, and the 'pure brow of the principle of Tawḥīd has received an impress of heathenism.' The remedy is to strip away this 'hard crust' and rediscover the original principles.
Second, Iqbal pivots from diagnosis to institutional application: how has the Grand National Assembly exercised ijtihād regarding the Caliphate? The Turkish position is that the Caliphate need not be vested in a single person but can be vested in 'a body of persons, or an elected Assembly' — a position Iqbal endorses as 'perfectly sound' and 'thoroughly consistent with the spirit of Islam.'
Third, Iqbal grounds this position in Ibn Khaldūn's classification of three views on the Universal Caliphate: that it is divinely mandated, that it is a matter of expediency, or that it is unnecessary. Turkey, he argues, has shifted from the first to the second view — the Muʿtazilite position that the Caliphate is expedient rather than divinely required — and has done so on the basis of historical experience: the idea of a Universal Caliphate 'has failed in practice,' has prevented rather than promoted Muslim unity, and has become 'a mere symbol of a power which departed long ago.'
Fourth, Iqbal invokes the precedent of Qāḍī Abū Bakr al-Bāqillānī, who dropped the condition that the Caliph must be from the Quraysh tribe when the Quraysh lost political power, and of Ibn Khaldūn himself, who acknowledged that when the Quraysh can no longer rule, the 'most powerful man' in a given territory must be accepted as Imām. This pragmatic adaptation of legal theory to historical reality is, for Iqbal, an exemplary instance of ijtihād — 'inspired by the realities of experience, and not by the scholastic reasoning of jurists who lived and thought under different conditions of life.'
This section is pivotal because it demonstrates what substantive ijtihād looks like in practice: not merely the assertion of the right to think independently (the Wahhābī limitation identified in Section 3) but the actual exercise of independent judgement on a major institutional question, grounded in historical analysis, responsive to changed circumstances, and justified by appeal to recognised authorities within the tradition itself.
