Since the middle of the twelfth century Hijri (eighteenth century C.E.) the Islamic world has been rapidly declining from its correct position and sinking horribly to the abyss of decline. Numerous attempts have been undertaken to revive it, or at least to halt the decline, but to no avail. The Islamic world remains in a state of gloom, anarchy and decline, and it still suffers the consequences of such backwardness and disorder.
The reason for its decline is due to one single factor, the severe weakness that destroyed the ability of the minds in understanding Islam. The cause for this weakness was the detachment of the capacity of the Arabic language from the capacity of Islam when the Arabic language was ignored both in understanding and carrying Islam from the beginning of the seventh century Hijri onwards. Accordingly, unless the capacity of the Arabic language is mixed with the capacity of Islam by making the Arabic language the language of Islam as a fundamental and inseparable part of it, the decline will continue to drag the Muslims down. This is because it is the linguistic capacity that carried the capacity of Islam and consequently intermingled with it, such that the perfect carrying of Islam cannot be undertaken except by it; and if it is neglected, Ijtihad (deriving of AHkam from texts) in Shar’a (divine law) cannot be undertaken. Knowledge of the Arabic language is a fundamental condition in Ijtihad. Furthermore Ijtihad is necessary for the Ummah since progress within the Ummah cannot occur except by utilising it.
There are three reasons why the attempts undertaken to revive the Muslims with Islam failed; The first is the lack of an accurate understanding of the Islamic fikrah (idea) by those who assumed the burden of revival. The second is the lack of clarity of the Tareeqah (method) of Islam in implementing its fikrah. The third is the failure of those who assumed the burden of revival to link the Islamic fikrah with the Islamic Tareeqah tightly and inseparably.
Accordingly all the reformist movements established to revive Muslims and to restore the glory of Islam failed. It was expected that such movements would fail, because though they were Islamic movements, they created even more complex issues, complicated the problems and distanced the society from Islam instead of working to implement Islam in it due to their misunderstanding of Islam.
It thus became necessary to have an Islamic movement that understands Islam as a fikrah and Tareeqah, to make the link between them and work to resume the Islamic way of life in any country of the Islamic world. This country would then become the starting point (nuqTat ibtidaa), from which the Islamic call springs, and then becomes the departure point (nuqTat inTilaq) for the call to Islam.
On this basis Hizb ut-Tahrir was established, and started to work for the resumption of the Islamic way of life in the Arab lands. This will result in the resumption of the Islamic way of life in the Islamic World by establishing the Islamic State in one or more of its countries as a support point (nuqTat irtikaz) for Islam. It would become a nucleus for the great Islamic State that resumes the Islamic way of life by the application of Islam completely in all Islamic lands and conveys the Islamic Da’wah to the entire world.
After study, thought and investigation, Hizb ut Tahrir adopted rules (AHkam Shara’iah), some of which relate to the treatment of individual problems that occur among individuals and in their relationship with each other, such as the prohibition of leasing land for farming. Some are relevant to the general opinions that are prevalent among Muslims and others (non Muslims), and others related to the relationship of Muslims with others (non Muslims), such as the permissibility of concluding emergency treaties (Mu’ahudat idtirariyyah) and the Da’wah for Islam before starting the fight etc. Some are related to the thoughts, which are rules (AHkam Sharai’ah) like the generally known rules such as collective principles and definitions, for example, the principle which says;
“That which is necessary to accomplish a duty (wajib) is itself a duty (wajib)”
And the definition of Hukm Shara’i as being, “the speech of the Legislator related to man’s actions” and so on.
