One of the facts Allah reveals in the Qur’an is that the universe has been created and that it will come to an end. The universe will, as will human beings and all other living things, come to an end. This appointed time is called the “Hour” in the Qur’an and it has been described in detail. The events that will happen prior to the Last Day have been revealed in the Qur'an. This fact is clearly understood from the verse: What are they awaiting but for the Hour to come upon them suddenly? Its signs have already come. What good will their Reminder be to them when it does arrive? (Surah Muhammad: 18) In order to understand the signs of this “great announcement” we must reflect upon the verses. Otherwise, as the verse indicates, our thinking will be of no use when the Last Day is suddenly upon us. Some of the hadiths of our Prophet (saas) deal with the signs of the Hour. In these hadiths of the Prophet (saas), there are both signs of the Hour and detailed information about the period just preceding it. This book examines the signs of the Hour through the verses of the Qur’an and hadiths of the Prophet (saas). and it shows the fact that these signs have begun to appear in our present time. It should also be kept in mind that Allah knows the truth about everything. as with all things, what we know about the end of the world comes only from what He has revealed to us.
