Muslim Prayer Times
The five Islamic prayers are named Fajr,
Zuhr, Asr, Maghrib and Isha. The timing of these five prayers varies from
place to place and from day to day. It is obligatory for Muslims to perform
these prayers at the correct time.
The prayer times for any given location on earth may be determined
mathematically if the latitude and longitude of the location are known.
However, the theoretical determination of prayer times is a lengthy process.
Much of this tedium may be alleviated by using computer programs.

Definition of prayer times
- FAJR starts with the dawn or morning twilight. Fajr ends just before sunrise.
- ZUHR begins after midday when the trailing limb of the sun has passed
the meridian. For convenience, many published prayer timetables add five
minutes to mid-day (zawal) to obtain the start of Zuhr. Zuhr ends at the
start of Asr time.
- The timing of ASR depends on the length of the shadow cast by an object.
According to the Shafi school of jurisprudence, Asr begins when the length
of the shadow of an object exceeds 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. In both cases, the minimum length
of shadow (which occurs when the sun passes the meridian) is subtracted
from the length of the shadow before comparing it with the length of the
object.
- MAGHRIB begins at sunset and ends at the start of isha.
- ISHA starts after dusk when the evening twilight disappears.
