One aspect Quranic miracle lies in foretelling future. Among the cases of such foretelling,  that of the conquest of Rum over Fars as mentioned in chapter Rum, has been viewed differently with regard to such various aspects as time of revelation, the situation and the place revealed in and the cause for Muslim`s joy. The paper, having sought to survey the positions of difference, has studied different views and presented a reasonable view in the field to overcome the differences. Chapter Rum has been ordered as the eighty fifth of Quranic chapters and thought as one revealed in Mecca. As is supported by historical studies, the length of time between defeat and conquest, the part in war, the date of defeat and the conquest  have been known to be respectively: eight years, Fars, seventh of be`sat and in the fifth and sixth years of Hijra. The cause for Muslims` joy has been viewed as appearance of the truth of Divine revelation and establishing what has been Divinely promised. The paper has relied upon Hafs narration of Asem to support the findings. Finally, the view of its revelation in Medina has been criticized based on lack of acceptable document.
