Ibn Rajab says regarding the hadith which states that “Islam is built upon five...” in his Jāmi‘ al-‘Ulūm wa al-Ḥikam: &nbsp;“What is meant is to strike the similitude of Islam as a building whose supports are these five, such that the building cannot stand firm without them. The rest of the attributes of Islam are added to the &nbsp;building to make it complete.” 
Ibn Hibban comments: “And this is what we say in our book, because when the Arabs mention something known in the language which has such &nbsp;enumeration, it does not mean that the listed number of matters is to the exclusion of all others.” 
So Islam cannot be limited to these five. It should also be noted that neither the word ‘pillars’ (arkān) nor the word ‘only’ (faqaṭ) is used in the hadith.

With the latest events in Afghanistan and the terrorist attacks by ISIS, the concept of an Islamic State or Caliphate is once again being discussed by the media in far from glowing terms. Interestingly, back in September 2015, the Daily Telegraph included a piece by the Syrian historian and former Carnegie scholar Sami Moubayed.
He pointed out that the Caliphate was mentioned in the Quran, and that the best response to the terrorists was to set up a modern Caliphate based on mainstream Islam.
This podcast will focus on the subject of the Caliphate and the views of the classical scholars.
