Dar Al-Muwaqqit
A Dar al-Muwaqqit (), or muvakkithane in Turkish, is a room or structure accompanying a mosque which was used by the '' muwaqqit'' or timekeeper, an officer charged with maintaining the correct times of prayer and communicating them to the muezzin (the person who issued the call to prayer). ''Dar al-Muwaqqit'' was the Arabic term given to such structures added to many mosques in Morocco from the Marinid period onward. In the Ottoman Empire the equivalent of such structures were known in Turkish as a ''muvakkithane'' ("lodge of the ''muwaqqit''"). Role of the Muwaqqit Muslims observe ''salah'', the daily ritual prayer, at prescribed times based on the hadith or the tradition of Muhammad (–632). Each day, there are five obligatory prayers with specific ranges of permitted times determined by daily astronomical phenomena. For example, the time for the maghrib prayer starts after sunset and ends when the red twilight has disappeared. Because the start and end times for prayers a ...

Time Zone
A time zone is an area which observes a uniform standard time for legal, Commerce, commercial and social purposes. Time zones tend to follow the boundaries between Country, countries and their Administrative division, subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time. All time zones are defined as offsets from Coordinated Universal Time (UTC), ranging from UTC−12:00 to UTC+14:00. The UTC offset, offsets are usually a whole number of hours, but a few zones are offset by an additional 30 or 45 minutes, such as in Indian Standard Time, India, Time in Australia, South Australia and Nepal Time, Nepal. Some areas of higher latitude use daylight saving time for about half of the year, typically by adding one hour to local time during spring (season), spring and summer. List of UTC offsets In the table below, the locations that use daylight saving time (DST) are listed in their UTC offse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abu Yusuf Yaqub Ibn Abd Al-Haqq
Abu Yusuf Yaqub ibn Abd al-Haqq () (c. 1212 – 20 March 1286) was a Marinid ruler of Morocco. He was the fourth son of Marinid founder Abd al-Haqq, and succeeded his brother Abu Yahya in 1258. He died in 1286. He was the son of Abd al-Haqq I and Oum el-Iman bint Ali el-Bethary, a Zenata woman. Some sources state his mother to be Oum el Youm, daughter of a clan leader of the Tafersit region. History The Marinids had been fighting the Almohads for supremacy over Morocco since the 1210s. At the time of Abu Yahya's death in July, 1258, the Marinids were installed in Fez and controlled eastern and northern Morocco, the Almohads reduced to the southerly districts around their capital, Marrakech. Although Abu Yahya had designated his son as successor in Fez, Abu Yusuf Yaqub, then a governor in Taza, managed, with only a little difficulty, to displace his nephew and get himself acknowledged as emir of the Marinids. In September, 1260, in a surprise attack, a Christian naval ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Clock
A water clock or clepsydra (; ; ) is a timepiece by which time is measured by the regulated flow of liquid into (inflow type) or out from (outflow type) a vessel, and where the amount is then measured. Water clocks are one of the oldest time-measuring instruments. The bowl-shaped outflow is the simplest form of a water clock and is known to have existed in Babylon, Egypt, and Persia around the 16th century BC. Other regions of the world, including India and China, also have early evidence of water clocks, but the earliest dates are less certain. Some authors, however, claim that water clocks appeared in China as early as 4000 BC. Water clocks were also used in ancient Greece and ancient Rome, described by technical writers such as Ctesibius and Vitruvius. Designs A water clock uses the flow of water to measure time. If viscosity is neglected, the physical principle required to study such clocks is Torricelli's law. There are two types of water clocks: inflow and outflo ...

Astrolabe
An astrolabe ( grc, ἀστρολάβος ; ar, ٱلأَسْطُرلاب ; persian, ستارهیاب ) is an ancient astronomical instrument that was a handheld model of the universe. Its various functions also make it an elaborate inclinometer and an analog calculation device capable of working out several kinds of problems in astronomy. In its simplest form it is a metal disc with a pattern of wires, cutouts, and perforations that allows a user to calculate astronomical positions precisely. Historically used by astronomers, it is able to measure the altitude above the horizon of a celestial body, day or night; it can be used to identify stars or planets, to determine local latitude given local time (and vice versa), to survey, or to triangulate. It was used in classical antiquity, the Islamic Golden Age, the European Middle Ages and the Age of Discovery for all these purposes. The astrolabe's importance comes not only from the early developments into the study of astron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mecca
Mecca (; officially Makkah al-Mukarramah, commonly shortened to Makkah ()) is a city and administrative center of the Mecca Province of Saudi Arabia, and the Holiest sites in Islam, holiest city in Islam. It is inland from Jeddah on the Red Sea, in a narrow valley above sea level. Its last recorded population was 1,578,722 in 2015. Its estimated metro population in 2020 is 2.042million, making it the List of cities in Saudi Arabia by population, third-most populated city in Saudi Arabia after Riyadh and Jeddah. Pilgrims more than triple this number every year during the Pilgrimage#Islam, pilgrimage, observed in the twelfth Islamic calendar, Hijri month of . Mecca is generally considered "the fountainhead and cradle of Islam". Mecca is revered in Islam as the birthplace of the Prophets and messengers in Islam, Islamic prophet Muhammad. The Hira cave atop the ("Mountain of Light"), just outside the city, is where Muslims believe the Quran was first revealed to Muhammad. Vis ...

Qibla
The qibla ( ar, قِبْلَة, links=no, lit=direction, translit=qiblah) is the direction towards the Kaaba in the Sacred Mosque in Mecca, which is used by Muslims in various religious contexts, particularly the direction of prayer for the salah. In Islam, the Kaaba is believed to be a sacred site built by prophets Abraham and Ishmael, and that its use as the qibla was ordained by Allah in several verses of the Quran revealed to Muhammad in the second Hijri year. Prior to this revelation, Muhammad and his followers in Medina faced Jerusalem for prayers. Most mosques contain a '' mihrab'' (a wall niche) that indicates the direction of the qibla. The qibla is also the direction for entering the ''ihram'' (sacred state for the hajj pilgrimage); the direction to which animals are turned during ''dhabihah'' (Islamic slaughter); the recommended direction to make ''dua'' (supplications); the direction to avoid when relieving oneself or spitting; and the direction to which the deceas ...

Islamic Calendar
The Hijri calendar ( ar, ٱلتَّقْوِيم ٱلْهِجْرِيّ, translit=al-taqwīm al-hijrī), also known in English as the Muslim calendar and Islamic calendar, is a lunar calendar consisting of 12 lunar months in a year of 354 or 355 days. It is used to determine the proper days of Islamic holidays and rituals, such as the Ramadan, annual fasting and the annual season for the Hajj, great pilgrimage. In almost all countries where the predominant religion is Islam, the civil calendar is the Gregorian calendar, with Assyrian calendar, Syriac month-names used in the Arabic names of calendar months#Levant and Mesopotamia, Levant and Mesopotamia (Iraq, Syria, Jordan, Lebanon and State of Palestine, Palestine) but the religious calendar is the Hijri one. This calendar enumerates the Hijri era, whose Epoch (reference date), epoch was established as the Islamic New Year in 622 Common Era, CE. During that year, Muhammad and his followers migrated from Mecca to Medina and es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sundial
A sundial is a horological device that tells the time of day (referred to as civil time in modern usage) when direct sunlight shines by the apparent position of the Sun in the sky. In the narrowest sense of the word, it consists of a flat plate (the ''dial'') and a gnomon, which casts a shadow onto the dial. As the Sun appears to move through the sky, the shadow aligns with different hour-lines, which are marked on the dial to indicate the time of day. The ''style'' is the time-telling edge of the gnomon, though a single point or ''nodus'' may be used. The gnomon casts a broad shadow; the shadow of the style shows the time. The gnomon may be a rod, wire, or elaborately decorated metal casting. The style must be parallel to the axis of the Earth's rotation for the sundial to be accurate throughout the year. The style's angle from horizontal is equal to the sundial's geographical latitude. The term ''sundial'' can refer to any device that uses the Sun's altitude or azimut ...

Quadrant (instrument)
A quadrant is an instrument used to measure angles up to 90°. Different versions of this instrument could be used to calculate various readings, such as longitude, latitude, and time of day. Its earliest recorded usage was in ancient India in Rigvedic times by Rishi Atri to observe a solar eclipse. It was then proposed by Ptolemy as a better kind of astrolabe. Several different variations of the instrument were later produced by medieval Muslim astronomers. Mural quadrants were important astronomical instruments in 18th-century European observatories, establishing a use for positional astronomy. Etymology The term ''quadrant'', meaning one fourth, refers to the fact that early versions of the instrument were derived from astrolabes. The quadrant condensed the workings of the astrolabe into an area one fourth the size of the astrolabe face; it was essentially a quarter of an astrolabe. History During Rigvedic times in ancient India, quadrants called 'Tureeyam's were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madrasa
Madrasa (, also , ; Arabic: مدرسة , pl. , ) is the Arabic word for any type of educational institution, secular or religious (of any religion), whether for elementary instruction or higher learning. The word is variously transliterated ''Madrasah arifah'', ''medresa'', ''madrassa'', ''madraza'', ''medrese'', etc. In countries outside the Arab world, the word usually refers to a specific type of religious school or college for the study of the religion of Islam, though this may not be the only subject studied. In an architectural and historical context, the term generally refers to a particular kind of institution in the historic Muslim world which primarily taught Islamic law and jurisprudence (''fiqh''), as well as other subjects on occasion. The origin of this type of institution is widely credited to Nizam al-Mulk, a vizier under the Seljuks in the 11th century, who was responsible for building the first network of official madrasas in Iran, Mesopotamia, and Khorasan. ...
