The Zuhr prayer (,   , "noon prayer"; also transliterated Duhr or Dhuhr) is the prayer after midday (but before the time for the Asr prayer.) It has been said that the name Dhuhr was given to this prayer because it falls halfway between two daily prayers, those being Fajr (or Fajer) which denotes the beginning of dawn and Isha, the first instant of complete darkness. Performed daily by practicing Muslims, it is the second of the five daily prayers (salat, known to be one of the most important pillars.) The Islamic day begins at Fajr which is the first prayer. The five daily prayers collectively are one of the Five Pillars of Islam in Sunni Islam, and one of the ten Practices of the Religion (furūʿ ad-dīn) (فروع الدين) according to Shia Islam. The Holy Qur'an has reiterated its importance, "Attend constantly to prayers and to the middle prayer and stand up truly obedient to Allah". It is reduced to two rakaʿāt when traveling.
