Özet

The exact time of many worship in Islam is depend on the appearance of some certain astronomical events. Some restricted times for worship, as well as makruh hours, are determined by the related celestial events. For instance; (i) start time of abstinence, i.e., beginning of fajr, (ii) sighting of crescent (Ru’yet-i Hilâl) moon, which adjusts the beginning of hijri months, (iii) the horizontal position of the Sun in the celestial sphere, which determines the preliminary and termination hours of the salah, the main worship, (iv) standing in the eve day in Arafat during Hajj, i.e., 9 Dhu'l-Hijja. Moreover, some prohibited (makruh) time intervals of performing any worship such as fasting in the Eid al Fitr and Eid al Adha, performing salah during sunset and sunrise, etc., are all defi ned by appearance of certain astronomical events. In this context, the implications of astronomical observations are very essential on Islamic opinions. In the present study, precise time determinations of dawn and fajr events performed on the basis of modern astronomical methods are given and interpreted.
