Qibla Observation By Shadows
Twice every year, the Sun culminates at the zenith of the ''Kaaba'' in Mecca, the holiest site in Islam, at local solar noon, allowing the qibla (the direction towards the ''Kaaba'') to be ascertained in other parts of the world by observing the shadows cast by vertical objects. This phenomenon occurs at 12:18 Saudi Arabia Standard Time (SAST; 09:18 UTC) on 27 or 28 May (depending on the year), and at 12:27 SAST (09:27 UTC) on 15 or 16 July (depending on the year). At these times, the Sun appears in the direction of Mecca, and shadows cast by vertical objects determine the qibla. At two other moments in the year, the Sun passes through the nadir (the antipodal zenith) of the ''Kaaba'', casting shadows that point in the opposite direction, and thus also determine the qibla. These occur on 12, 13, or 14 January at 00:30 SAST (21:30 UTC on the preceding day), and 28 or 29 November at 00:09 SAST (21:09 UTC on the preceding day). The shadow points towards Mecca because the Sun path ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subsolar Point
The subsolar point on a planet or a moon is the point at which its Sun is perceived to be directly overhead (at the zenith); that is, where the Sun's rays strike the planet exactly perpendicular to its surface. The subsolar point occurs at the location on a planet or a moon where the Sun culminates at the location's zenith. This occurs at solar noon. At this point, the Sun's rays will fall exactly vertical relative to an object on the ground and thus cast no observable shadow. To an observer on a planet with an orientation and rotation similar to those of Earth, the subsolar point will appear to move westward with a speed of 1600 km/h, completing one circuit around the globe each day, approximately moving along the equator. However, it will also move north and south between the tropics over the course of a year, so will appear to spiral like a helix. The term subsolar point can also mean the point closest to the Sun on an astronomical object, even though the Sun might no ...

Saudi Arabia Standard Time
Saudi Arabia Standard Time (), abbreviated as SAST, is the standard time zone of Saudi Arabia. The time zone is 3 hours ahead of UTC ( UTC+03:00) with no daylight savings. SAST is defined by the 45th Meridian East. Before a standardized time zone was introduced, the country used ''Arabic time'', in which clocks were set to midnight at sundown. Because of confusion between various other systems also used in the kingdom, the standardized use of a time zone was established. History Until 1968, Saudi Arabia used ''Arabic time,'' where clocks were set to 12 o'clock at sunset or when the call to prayer for the sunset prayer was heard. This was because the Islamic calendar defines sunset as marking the beginning of a new day. However this later conflicted with the introduction of western sun time, which defined, in congruence with Europe, the start of a new day to be midnight. With western sun time, clocks were set to six o'clock at sun set. While western sun time was intended to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Calendar
A solar calendar is a calendar whose dates indicates the season or almost equivalently the apparent position of the Sun relative to the stars. The Gregorian calendar, widely accepted as a standard in the world, is an example of a solar calendar. The main other types of calendar are lunar calendar and lunisolar calendar, whose months correspond to cycles of Moon phases. The months of the Gregorian calendar do not correspond to cycles of the Moon phase. The Egyptians appear to have been the first to develop a solar calendar, using as a fixed point the annual sunrise reappearance of the Dog Star— Sirius, or Sothis—in the eastern sky, which coincided with the annual flooding of the Nile River. They constructed a calendar of 365 days, consisting of 12 months of 30 days each, with 5 days added at the year’s end. The Egyptians’ failure to account for the extra fraction of a day, however, caused their calendar to drift gradually into error. Examples The oldest solar calendar ...

Local Meridian
In astronomy, the meridian is the great circle passing through the celestial poles, as well as the zenith and nadir of an observer's location. Consequently, it contains also the north and south points on the horizon, and it is perpendicular to the celestial equator and horizon. Meridians, celestial and geographical, are determined by the pencil of planes passing through the Earth's rotation axis. For a location ''not'' on this axis, there is a unique meridian plane in this axial-pencil through that location. The intersection of this plane with Earth's surface defines two '' geographical meridians'' (either one east and one west of the prime meridian, or else the prime meridian itself and its anti-meridian), and the intersection of the plane with the celestial sphere is the celestial meridian for that location and time. There are several ways to divide the meridian into semicircles. In one approach, the observer's upper meridian extends from a celestial pole and passes through t ...

North Season
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating Direction (geometry), direction or geography. Etymology The word ''north'' is etymology, related to the Old High German ''nord'', both descending from the Proto-Indo-European language, Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Ancient Greek, Greek ''boreas'' "north wind, north" which, according to Ovid, was personified as the wind-god Boreas (god), Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomy In The Medieval Islamic World
Medieval Islamic astronomy comprises the astronomical developments made in the Islamic world, particularly during the Islamic Golden Age (9th–13th centuries), and mostly written in the Arabic language. These developments mostly took place in the Middle East, Central Asia, Al-Andalus, and North Africa, and later in the Far East and India. It closely parallels the genesis of other Islamic sciences in its assimilation of foreign material and the amalgamation of the disparate elements of that material to create a science with Islamic characteristics. These included Greek, Sassanid, and Indian works in particular, which were translated and built upon. Islamic astronomy played a significant role in the revival of ancient astronomy following the loss of knowledge during the early medieval period, notably with the production of Latin translations of Arabic works during the 12th century. A significant number of stars in the sky, such as Aldebaran, Altair and Deneb, and astrono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salat
''Salah'' (, also spelled ''salat'') is the practice of formal ibadah, worship in Islam, consisting of a series of ritual prayers performed at prescribed times daily. These prayers, which consist of units known as rak'a, ''rak'ah'', include a specific set of physical postures, recitation from the Quran, and prayers from the Sunnah, and are performed while facing the direction towards the Kaaba in Mecca (''qibla''). The number of ''rak'ah'' varies depending on the specific prayer. Variations in practice are observed among adherents of different ''Madhhab, madhahib'' (schools of Islamic jurisprudence). The term ''salah'' may denote worship in general or specifically refer to the obligatory prayers performed by Muslims five times daily, or, in some traditions, three times daily.Jafarli, Durdana.

In Islamic terminology ''sharīʿah'' refers to immutable, intangible divine law; contrary to ''fiqh'', which refers to its interpretations by Ulama, Islamic scholars. Sharia, or fiqh as traditionally known, has always been used alongside urf, customary law from the very beginning in Islamic history; has been elaborated and developed over the centuries by fatwa, legal opinions issued by mufti, qualified jurists – reflecting the tendencies of Schools of Fiqh, different schools – and integrated and with various economic, penal and administrative laws issued by Muslims, Muslim rulers; and implemented for centuries by Qadi, judges in the courts until recent times, when secularism was widely adopted in Islamic societies.
