“The Caliphate is for Allah (subhanahu wa ta’aala); He is the one who decrees for it to be established and this will occur when a member of the family of the Messenger of Allah (sallallahu ‘alayhi wassallam) appears, and he is the Mahdi, who will prepare the way for the descension of Jesus (alaihis-salaam). Yes, this is the Caliphate that will exist.
So it will exist when Allah wills and not when we wish for it to happen. As for them saying that they are working for the establishment of the Caliphate, then this action is flawed and rejected, and it is a corrupt intention. It is impermissible for them to call to Allah based on this intention. For indeed they solely intend with this call of theirs to enter into the realm of politics and to attain leadership.”
Shaykh Ahmad an-Najmi (d.1429H) from the book The Precise Verdicts Regarding Deviant Methodologies, Sunnah Publishing, First Edition, page 26.
“Even the so-called Caliphate (or Khilafah) of the Ottomans had its fair share of secular laws. In 1858 for example, it introduced a penal code based upon an earlier French Napoleonic Code which discarded the prescribed Islamic Punishments. In 1875 the secular Istanbul Law Faculty was instituted to train judges and lawyers from non-Islamic courts of the empire. Ottoman history is littered with examples of cooperation, aid and assistance in battles from the colonial powers such as the British and the French. So is this the Caliphate that al-Muhajiroun and their neo-Kharijite allies lament over? The Caliphate that they claim was dismantled on March 3rd, 1924? It shows their lack of knowledge and inexperience even in rudiments of Islamic history. They yearn for a period in Islamic history that they themselves would have rebelled against!”
