ts aim is to resume the Islamic way of life and to convey the Islamic Call to the world. This objective means bringing the Muslims back to living an Islamic way of life in Dar al-Islam (the domain of Islam) and in an Islamic society such that all of life's affairs in society are administered according to the Shari'ah rules

Hizb ut-Tahrir is a political party whose ideology is Islam, so politics is its work and Islam is its ideology. It works within the Islamic Ummah and together with her, so that she adopts Islam as her cause and is led to restore the Khilafah "Caliphate" and the ruling by what Allah revealed. Hizb ut-Tahrir is a political group and not a priestly one. Nor is it an academic, educational or a charity group. The Islamic thought is the soul of its body, its core and the secret of its life. Hizb ut-Tahrir started its work in al-Quds (Jerusalem) in 1953 under the leadership of its founder, the honourable scholar, thinker, able politician, and judge in the Court of Appeals in al-Quds (Jerusalem), Taqiuddin 
an-Nabhani.

As you are well aware that for a long time we have not sent any delegations to you nor have we corresponded with you demanding your support for establishing al-Khilafah "Caliphate" ar-Rashidah. This was because we have been witnessing with our own eyes and ears that you have indeed abandoned the Khilafah "Caliphate" behind your backs and you are violating the authentic Shari'ah evidences
