SUBJECT AND OBJECTIVES : The Big Bang theory and the standard cosmological models based on it imply the world’s temporal finitude. The temporally finite universe, most physicists believe, must have been created out of nothing. In order to avoid the theological and metaphysical implications of such an idea, the most important scenarios that have been proposed are: (1) The universe is not temporally finite, but rather is pre-eternal; (2) The creation of the universe out of nothing can be explained purely physically; (3) There is no correlation between the temporal finitude of the universe and having a temporal beginning, so the universe always existed; (4) The creation of the universe as a brute fact is a spontaneous uncaused origination ex nihilo. METHOD AND FINDING : In this essay, I aim to discuss and criticize scenario (2). To reach this aim, two important physical models, i.e: The Tryon-Vilenkin and Hawking-Hartle models, which have been formulated based on quantum fluctuation, will be explained. It will be shown that they are indeed explaining the creation of the universe, not out of nothing, but from something. CONCLUSION : No physical theory can ever explain the creation of the universe out of nothing by appealing to the physical phenomena or the laws of nature. The outcome of the paper is that creatio ex nihilo of the universe out of nothing can only be explained metaphysically by appealing to some external causes.

The word “Shahr” is an important word in the calendar system of the Qur'an. As the main element of the Qur’an, words have a special place within its text. Therefore, studying and analyzing the meaning of Qur’anic words is a necessary method of understanding and correct interpretation of verses. This article aims to investigate the meaning of the word shahr in the Qur'an based on a descriptive-analytical method; Explaining the literal and idiomatic meaning, the application of this word in the Qur'an are as follows: the time to do or leave a certain task, measurement tool for valuing a specific phenomenon, one of the main bases of the calendar, and expressing God's genesis law in the number of months of the year. Some of the examples of shahr in the Qur'an are specific, meaning the crescent moon. In the cases where there is no specific example, it means the crescent moon in the customary and literal sense, which in order to observe caution and make calculations easier in custom, it is also used to mean a numerical month (30 days). Since God has based the guidance and development of humans on time, at the end of some of the discussed verses, God speaks about the piety and the need to pay attention to Divine limits, such as observing the limits of certain months and their rules
