In your speech you quoted the Companion Abu Bakr Al-Siddiq: ‘I have been given authority over you, and I am not the best of you.’ This begs the question: who gave you authority over the Ummah? Was it your group? If this is the case then a group of no more than several thousand has appointed itself the ruler of over billion and a half Muslims. This attitude is based upon a corrupt logic that says: ‘Only we are Muslims, and we decide who the caliph is, we have chosen one and so whoever does not accept our caliph is not a Muslim.’ In this case, a caliph is nothing more than the leader of a certain group that declares more than 99% of Muslims non-Muslim. On the other hand, if you recognize the billion and a half people who consider themselves Muslims, how can you not consult (shura) them regarding your so-called caliphate? Thus, you face one of the two conclusions: either you concur that they are Muslims and they did not appoint you caliph over them – in which case you are not the caliph – or, the other conclusion is that you do not accept them as Muslims, in which case Muslims are a small group not in need of a caliph, so why use the word ‘caliph’ at all? In truth, the caliphate must emerge from a consensus of Muslim countries, organizations of Islamic scholars and Muslims across the globe.
