It seems that there is no way for salvation other than Islam for the world. The whole world now is talking about Islam. All the ideologies were tried and they are done. Marxism, fascism, capitalism are over. They tried all of them. The whole human race is stricken by these ideologies; they are suffering. But Islam is fresh and it is apparent that Islam will surely refresh every place it goes. Without Islam, people commit suicide; the world commits suicide. Plants wither, animals die, and people die.
Islam is life. It is an understanding of life. To be alive, to live normally there is certainly need for Islam. God created in that way. There is a prospectus with a medicine, right? There is a description for how to use a technical tool. God informed us on how to use the world with a Book. If we don’t perform it, the world will be laid to waste. If people are a law unto themselves, the world will be ruined. If they had acted upon Quran, the world would have been a paradise. The world will be a paradise once for the last time (during the age of Mahdi). Afterwards, it will be ruined again (before the doomsday).
