Prayer times on your mobile phone


User Guide

  • The prayers
On the basis of the various below parameters, Mobile Muezzin uses complex astronomical formulas to determine precisely the five islamic prayer times, regarding when:
  • Morning's dawn or twilight starts - Fajr,
  • The sun rises - Shuruq,
  • The trailing limb of the sun has passed the meridian - Zuhr,
  • The shadow cast by an object equals a certain a length - Asr,
  • The sun sets - Maghrib,
  • Evening's dusk or twilight disappears - Isha,


Sun position
The relative position of the sun depends fundamentally of the user's position (the observant) as well as the related date of observation. Therefore, it is mandatory for the user to know precisely the latitude, longitude and altitude as well as the related applicable timezone in that area.

Mobile Muezzin allows to the Muslim observant to drastically alleviate this complexity, thanks to a rich database collecting those parameters for more than 5 million locations worldwide. You simply have to enter the country and  location name, and Mobile Muezzin automatically calculates the prayer hours for that position (refer to the Location chapter).

Religious organization
In the Islamic world, a certain number of Religious organizations propose a set of calculation methods for the prayers schedule determination. The main difference between the organizations resides in the "Fajr" and "Isha" prayers. The angle between the horizon, the twilights and the observant position determines the start of the mentioned prayers. This angle varies of the amplitude of a few degrees from an organization to another and has thus, an impact on the prayer's schedule. It is recommended to select the nearest organization to your place of residence.

Mobile Muezzin adapts the prayer times calculation according to the default religious reference organization to which the country is affiliated. It gives also the possibility to the muslim observant to change this default selection, if needed.

Juristic method
Various juristic or «Fiqh» schools, of which the Hanafi, Shafii, Maliki or Hanbali coexist. They attempt to provide to the Islamic community, a theologic interpretation of the sources of Islam such as the Quran, the Sunna or the hadiths. Despite major similarities, some opinions may diverge from a school to another, mainly because of differences on the reasoning methods used by each. It is the case for the "Asr" prayer that begins, according to the Shafi, Mailki and Hanbali Schools of jurisprudence, when the length of the shadow of an object equals the length of the object. According to the Hanafi School of jurisprudence, "Asr" begins when the length of the shadow exceeds twice the length of the object.

Mobile Muezzin calculates the prayers schedule and gives the observant the opportunity to take into consideration the juristic method to which he belongs. Please refer to the "Profile" chapter to know how to select the correct juristic method for the prayer calculation.
