the heavens and the earth and what is between them (see, e.g., Quran , , , etc.). All human beings are equal in their utter dependence upon God, and their well-being depends upon their acknowledging that fact and living accordingly. The Quran uses cosmological and contingency arguments in various verses without referring to the terms to prove the existence of God. Therefore, the universe is originated and needs an originator, and whatever exists must have a sufficient cause for its existence. Besides, the design of the universe is frequently referred to as a point of contemplation: "It is He who has created seven heavens in harmony. You cannot see any fault in God's creation; then look again: Can you see any flaw?" Eschatology The doctrine of the last day and eschatology (the final fate of the universe) may be considered the second great doctrine of the Quran. It is estimated that approximately one-third of the Quran is eschatological, dealing with the afterlife in the next world and with the day of judgment at the end of time. There is a reference to the afterlife on most pages of the Quran and belief in the afterlife is often referred to in conjunction with belief in God as in the common expression: "Believe in God and the last day." A number of suras such as 44, 56, 75, 78, 81 and 101 are directly related to the afterlife and its preparations. Some suras indicate the closeness of the event and warn people to be prepared for the imminent day. For instance, the first verses of Sura 22, which deal with the mighty earthquake and the situations of people on that day, represent this style of divine address: "O People! Be respectful to your Lord. The earthquake of the Hour is a mighty thing." The Quran is often vivid in its depiction of what will happen at the end time. Watt describes the Quranic view of End Time:The climax of history, when the present world comes to an end, is referred to in various ways. It is 'the Day of Judgment,' 'the Last Day,' 'the Day of Resurrection,' or simply 'the Hour.' Less frequently it is 'the Day of Distinction' (when the good are separated from the evil), 'the Day of the Gathering' (of men to the presence of God) or 'the Day of the Meeting' (of men with God). The Hour comes
