Dini Rahmadani S, Fadhil Asami Toat

Abstract


Asr prayer is one of the prayers that existed before the time of the Prophet Muhammad. The initial criteria for the time of Asr prayer were delivered by the angel Gabriel with two criteria related to the length of the shadow of an object. The initial criterion and the second criterion textually give a different picture. The author conducted research to find out the similarity of these criteria through a Mathematical and Astronomical review of. It was found that in the first criterion (when the shadow of something is the same as it) when the Sun is at the hour angle at about 46-51 degrees when the information on the asr time criterion is conveyed. The height of the Sun will be different and meet the criteria of the length of the shadow produced each day.
