ADNAN OKTAR: But of course, in the destiny, the Unity of Islam is not possible without Hazrat Mahdi (pbuh). People are striving to establish the Unity of Islam for about 100 years, but it does not happen. It would have happened if it were meant to be. Without Hazrat Mahdi (pbuh) it is not posible, it is impossible.  That would be waging war against the Messenger of Allah (saas). If you say; "there is no need for Hazrat Mahdi (pbuh), I can do it myself"; that would mean saying; "[May Allah forbid] the Messenger of Allah (pbuh) is talking in vain, Allah had revealed those to him for no reason". Allah had described how it would happen and He had unrolled the whole plan of the history in front of us with all the details, He had laid out the map of the history.  He says; "he [Hazrat Mahdi (pbuh)], will come at this date, he will have such and such characteristics, you will abide by him like this, you will get such and such results." If a person says "this does not interest me", he cannot be successful. But despite of all these, the system of the Mahdi will be successful, insha'Allah. Even if there are people acting in the contrary, the system of the Mahdi will be successful. It is successful, and it will continue to be so, insha'Allah.
