There is a Hadith of the Prophet which says that the word of God would enter every home in the world. This was interpreted as a concept of Caliphate in the sense that the rule of Islam would be established all over the world. This is illogical and baseless. The Hadith refers to the 'word of Islam’, not the ‘rule of Islam’. It is obvious that, according to this Hadith, the word of Islam, or its message, will reach all homes, but this is far from Muslim rule being established all over the world!

This (mis)interpretation is not an explanation, but, rather, a politicization of this Hadith report. Muslims have begun to take great pride in saying that Islam is a complete system. This may seem like a beautiful definition of Islam, but it is a later addition (bid‘a), and has nothing to do with the original Islam. Nowhere in the Quran and Hadith do we find anything to suggest that Islam is a total system.
