The natural guarantee for implementing Islam, carrying of its Da’wah, continuity of its implementation and the perfection of this implementation is the Taqwa of the ruler and the concentration of this Taqwa within himself. This is because the Taqwa of Allah by the ruler makes Him more concerned about Islam than his concern for his own life and his own needs. It also generates in Him the sensitive feeling that makes Him remember Allah within himself every time He undertakes an action, and fear Allah regarding every one of his conducts.

If the ruler lost the Taqwa, then He would have lost the natural guarantee for the implementation of Islam, improving its application and the continuity of this application, and He would have lost the guarantee to carry the Islamic Da’wah. Since it is possible for the Taqwa to elude the ruler, then there must be a physical means that compels Him to implement (Islam) upon the land and has the authority to establish in his place the ruler who implement Islam and carries its Da’wah. This practical means is the Ummah. Therefore it is obligatory upon the Islamic Ummah, if she saw an unjust ruler, violating the sanctity of Allah, breaking the covenant of Allah, opposing the Sunnah of Rasool Allah, treating the servants of Allah with sin and transgression, she must challenge Him by word and by action, or change him. In order that the Ummah undertakes this duty, she must be characterised with the Taqwa of Allah, because the fear of the Ummah from Allah generates the concern about Islam and its implementation. This obliges her to account the ruler about his actions, so she argues/discusses with Him and accounts Him whenever she sees from Him any shortcomings in the implementation or an attempt to deviate from the Ahkam (rules) of Islam, or misapplies the systems of Islam. By such means, the application of Islam continues as well as the improvement of its application can follow.

However the Ummah-which is the practical means in the Dunya to implement Islam through her watching over and accounting the rulerneeds a correct structure to be established within her. This correct structure should be based on Islam, distinct in its deep understanding and its great fear of Allah. This is because it is established on one basis, which is the Islamic ‘aqeedah, and works to culture the people with the concentrated Islamic culture (Thaqaafah). It is a culture that broadens the scope of mind, and strengthens the comprehension, and purified the soul; for it links the emotions with the thought, and it generates harmony between the thoughts and the emotions. This makes of the Muslim the required Islamic personality. Once this structure was established in accordance with this personality, it would be the means to mould the Ummah. This is because Islam purifies her thoughts, and moulds her in one thought and thus drives her to one objective, where she lives for its sake and carries the Da’wah to it. Then she would be continually vigilant about the ideology that she carries and would be well aware of it. What awakens her is this structure that lives for the sake of the ideology, for the sake of the Da’wah to it and for the sake of the implementation of this ideology and the continuity of its implementation.
