system comes from the Creator", who has "better insight into the human condition than humans." Jihad HT texts define Jihad as "war undertaken for the sake of Allah (swt) to raise high His (swt) word" and requiring an army (Institutions of State in the Khilafah). They declare the necessity of jihad so that Da'wah will be carried "to all mankind" and will "bring them into the Khilafah state," and the importance of declaring "Jihad against the Kuffar without any lenience or hesitation;" (Ummah's Charter), as well as the need to fight unbelievers who refuse to be ruled by Islam, even if they pay tribute (The Islamic Personality). On the other hand, public statements by Hizb ut-Tahrir deny this by saying "Hizb ut-Tahrir will be permitted to engage in an armed struggle when the Caliphate re-emerges, ... The party is not waiting for any order to begin an `armed struggle`". Other HT texts differ over whether jihad is by nature offensive rather than defensive (supported in The Inevitability of the Clash of Civilisations), or encompasses both "defensive and offensive war" (supported on a different page of The Inevitability of the Clash of Civilisations). Statements also conflict as to whether offensive jihad must wait for the caliphate to be established (as the head of HT Britain, Jalaluddin Patel, told an interviewer in 2004), or requires only an "amir" to lead Muslims (Hizb ut-Tahrir pamphlet). The party does support "defensive jihad" in Iraq and Afghanistan against American occupation—defensive jihad not requiring the "appropriate political and military capabilities" of an Islamic State, it need not wait for either a caliph or amir. Shariah Along with the establishment of an Islamic State, Hizb ut-Tahrir's other main principle/objective is the enforcement of shariah law to regulate all aspects of human life— politics, economics, sciences, and ethics. The law will be based upon fair interpretations of the Qur'an, the Sunnah, consensus of the companions (Ijma al-Sahaba), and legitimate analogies (Qiyas) drawn from those three sources. The Islamic state will not "adopt a particular" Madhhab (school of fiqh). According to Forum 18 News Service, it was told by an HT representative that "the only true Muslims" are those who adhere to one of the four Sunni madhhabs, and "those who depart" the four "would be considered as apostates and liable to punishment according to Islamic law." Regarding traditional hudud penal code, the HT text Concepts of Hizb ut-Tahrir
