Qibla Observation By Shadows
Twice every year, the Sun culmination, culminates at the zenith of the ''Kaaba'' in Mecca, the Holiest sites in Islam, 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 point, 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 ...

Saudi Arabia Standard Time
Saudi Arabia Standard Time ( ar, التوقيت القياسي السعودي, At-Tawqīt al-qiyāsiyy as-suʿūdiyy), 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, ...

Solar Calendar
A solar calendar is a calendar whose dates indicate 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 type of calendar is a lunar 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 calendars include the Julian calendar a ...

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'' at a geographical pole, there is a unique meridian plane in this axial-pencil through that location. The intersection of this plane with Earth's surface is the '' geographical 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 the horizontal coordinate system, the observer's meridian is divided into halves terminated by the horizon's north and south points. The observer's upper meridian passes through the zenith while the lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diurnal Motion
Diurnal motion (, ) is an astronomical term referring to the apparent motion of celestial objects (e.g. the Sun and stars) around Earth, or more precisely around the two celestial poles, over the course of one day. It is caused by Earth's rotation around its axis, so almost every star appears to follow a circular arc path, called the diurnal circle, often depicted in star trail photography. The time for one complete rotation is 23 hours, 56 minutes, and 4.09 seconds – one sidereal day. The first experimental demonstration of this motion was conducted by Léon Foucault. Because Earth orbits the Sun once a year, the sidereal time at any given place and time will gain about four minutes against local civil time, every 24 hours, until, after a year has passed, one additional sidereal "day" has elapsed compared to the number of solar days that have gone by. Relative direction The relative direction of diurnal motion in the Northern Celestial Hemisphere are as follows: * Facing nort ...

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 ''Anemoi#Boreas, boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Anemoi#Boreas, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomy In The Medieval Islamic World
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 Byzantine and EuropeanSaliba (1999). 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. Islamic astronomy also had an influence on Chinese astronomy and Malian a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Folk Knowledge
Traditional knowledge (TK), indigenous knowledge (IK) and local knowledge generally refer to knowledge systems embedded in the cultural traditions of regional, indigenous, or local communities. According to the World Intellectual Property Organization (WIPO) and the United Nations (UN), traditional knowledge and traditional cultural expressions (TCE) are both types of indigenous knowledge. Traditional knowledge includes types of knowledge about traditional technologies of subsistence (e.g. tools and techniques for hunting or agriculture), midwifery, ethnobotany and ecological knowledge, traditional medicine, celestial navigation, craft skills, ethnoastronomy, climate, and others. These kinds of knowledge, crucial for subsistence and survival, are generally based on accumulations of empirical observation and on interaction with the environment. In many cases, traditional knowledge has been passed for generations from person to person, as an oral tradition. Some forms of traditio ...

Sharia
Sharia (; ar, شريعة, sharīʿa ) is a body of religious law that forms a part of the Islamic tradition. It is derived from the religious precepts of Islam and is based on the sacred scriptures of Islam, particularly the Quran and the Hadith. In Arabic, the term ''sharīʿah'' refers to God's immutable divine law and is contrasted with ''fiqh'', which refers to its human scholarly interpretations. In the historical course, fiqh sects have emerged that reflect the preferences of certain societies and state administrations on behalf of people who are interested in the theoretical (method) and practical application (Ahkam / fatwa) studies of laws and rules, but sharia has never been a valid legal system on its own. It has been used together with " customary (Urf) law" since Omar or the Umayyads. It may also be wrong to think that the Sharia, as a religious argument or belief, is entirely within or related to Allah's commands and prohibitions. Several non-graded crimes are ...
