Qiblah
The qibla () 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 God 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 (a wall niche) that indicates the direction of the qibla. The qibla is also the direction for entering the (sacred state for the hajj pilgrimage); the direction to which animals are turned during (Islamic slaughter); the recommended direction to make (supplications); the direction to avoid when relieving oneself or spitting; and the direction to which the deceased are aligned when buried. The qibla may be observed facing the Kaaba accurately () or facing in the g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mosque
A mosque ( ), also called a masjid ( ), is a place of worship for Muslims. The term usually refers to a covered building, but can be any place where Salah, Islamic prayers are performed; such as an outdoor courtyard. Originally, mosques were simple places of prayer for the early Muslims, and may have been open spaces rather than elaborate buildings. In the first stage of Islamic architecture (650–750 CE), early mosques comprised open and closed covered spaces enclosed by walls, often with minarets, from which the Adhan, Islamic call to prayer was issued on a daily basis. It is typical of mosque buildings to have a special ornamental niche (a ''mihrab'') set into the wall in the direction of the city of Mecca (the ''qibla''), which Muslims must face during prayer, as well as a facility for ritual cleansing (''wudu''). The pulpit (''minbar''), from which public sermons (''khutbah'') are delivered on the event of Friday prayer, was, in earlier times, characteristic of the central ...

Du'a
In Islam, ( , plural: ' ) is a prayer of invocation, supplication or request, asking help or assistance from God in Islam, God. Duʿāʾ is an integral aspect of Islamic worship and spirituality, serving as a direct line of communication between a believer and Allah. Unlike the formal five daily prayers (Salah) which have specific timings and rituals, duʿāʾ is more flexible and can be made at any time and in any place. Through duʿāʾ, Muslims affirm their dependence on Allah and their trust in His wisdom and mercy. A special position of prayers are prayers of Sufi-Masters, the ''mustajaab ad-du'a'', prayers answered immediately. Requirements for these prayers are that the Sufi is never asking God for worldly but only for spiritual requests. In times of sickness, danger, or drought, they were answered, while their prayers could also punish those who oppose them. Role in Islam Muslims regard dua as a profound act of worship. Muhammad is reported to have said, " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaaba 2
The Kaaba (), also spelled Kaba, Kabah or Kabah, sometimes referred to as al-Kaba al-Musharrafa (), is a stone building at the center of Islam's most important mosque and holiest site, the Masjid al-Haram in Mecca, Saudi Arabia. It is considered by Muslims to be the ''Baytullah'' () and determines the qibla () for Muslims around the world. In early Islam, Muslims faced in the general direction of Al-Aqsa Mosque in Jerusalem as the qibla in their prayers before changing the direction to face the Kaaba, believed by Muslims to be a result of a Quranic verse revelation to Muhammad. According to Islam, the Kaaba was rebuilt several times throughout history, most famously by Ibrahim and his son Ismail, when he returned to the valley of Mecca several years after leaving his wife Hajar and Ismail there upon Allah's command. The current structure was built after the original building was damaged by a fire during the siege of Mecca by the Umayyads in 683 CE. Circling the ''Kaa ...

Hajj
Hajj (; ; also spelled Hadj, Haj or Haji) is an annual Islamic pilgrimage to Mecca, Saudi Arabia, the holiest city for Muslims. Hajj is a mandatory religious duty for capable Muslims that must be carried out at least once in their lifetime by all adult Muslims who are physically and financially capable of undertaking the journey, and of supporting their family during their absence from home. In Islamic terminology, Hajj is a pilgrimage made to the Kaaba, the "House of Allah", in the sacred city of Mecca in Saudi Arabia. It is one of the Five Pillars of Islam, alongside (oath that one believes there is no god but Allah), (prayer), (almsgiving), and (fasting during Ramadan). The Hajj is an annual practice when Muslim brotherhood is on display and their solidarity with fellow Muslim people and submission to God (Allah) is fulfilled. The Hajj is taken by Muslims to cleanse their souls of all worldly sins, which connotes both the outward act of a journey after death and th ...

Islamic Astronomy
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] |
Companions Of The Prophet
The Companions of the Prophet () were the Muslim disciples and followers of the Islamic prophet Muhammad who saw or met him during his lifetime. The companions played a major role in Muslim battles, society, hadith narration, and governance during and after the life of Muhammad. The era of the companions began following the death of Muhammad in 632 CE, and ended in 110 AH (728 CE) when the last companion Abu al-Tufayl died. Later Islamic scholars accepted their testimony of the words and deeds of Muhammad, the occasions on which the Quran was revealed and other important matters in Islamic history and practice. The testimony of the companions, as it was passed down through trusted chains of narrators ('' asānīd''), was the basis of the developing Islamic tradition. From the traditions (''hadith'') of the life of Muhammad and his companions are drawn the Muslim way of life (''sunnah''), the code of conduct (''sharia'') it requires, and Islamic jurisprudence (''fiqh''). ...

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] |
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] |
Qibla Compass
A qibla (qiblah) compass (sometimes also called qibla/qiblah indicator or ''qiblanuma'') is a modified compass used by Muslims to indicate the direction to face to perform prayers. In Islam, this direction is called qibla, and points towards the city of Mecca and specifically to the Kaaba. While the compass, like any other compass, points north, the direction of prayer is indicated by marks on the perimeter of the dial, corresponding to different cities, or by a second pointer set by the user according to their own location. To determine the proper direction, one has to know with some precision both the longitude and latitude of one's own location and those of Mecca, the city toward which one must face. Once that is determined, the values are applied to a spherical triangle, and the angle from the local meridian to the required direction of Mecca can be determined. The indicator usually consists of a round brass box with a hinged lid and an inset magnetic compass. A list of impo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobile App
A mobile application or app is a computer program or software application designed to run on a mobile device such as a smartphone, phone, tablet computer, tablet, or smartwatch, watch. Mobile applications often stand in contrast to desktop applications which are designed to run on desktop computers, and web applications which run in mobile web browsers rather than directly on the mobile device. Apps were originally intended for productivity assistance such as email, calendar, and contact databases, but the public demand for apps caused rapid expansion into other areas such as mobile games, factory automation, GPS and location-based services, order-tracking, and ticket purchases, so that there are now millions of apps available. Many apps require Internet access. Apps are generally downloaded from app stores, which are a type of digital distribution platforms. The term "app", short for "Application software, application", has since become very popular; in 2010, it was listed as " ...

Formula
In science, a formula is a concise way of expressing information symbolically, as in a mathematical formula or a ''chemical formula''. The informal use of the term ''formula'' in science refers to the general construct of a relationship between given quantities. The plural of ''formula'' can be either ''formulas'' (from the most common English plural noun form) or, under the influence of scientific Latin, ''formulae'' (from the original Latin). In mathematics In mathematics, a formula generally refers to an equation or inequality relating one mathematical expression to another, with the most important ones being mathematical theorems. For example, determining the volume of a sphere requires a significant amount of integral calculus or its geometrical analogue, the method of exhaustion. However, having done this once in terms of some parameter (the radius for example), mathematicians have produced a formula to describe the volume of a sphere in terms of its radius: ...

Spherical Trigonometry
Spherical trigonometry is the branch of spherical geometry that deals with the metrical relationships between the edge (geometry), sides and angles of spherical triangles, traditionally expressed using trigonometric functions. On the sphere, geodesics are great circles. Spherical trigonometry is of great importance for calculations in astronomy, geodesy, and navigation. The origins of spherical trigonometry in Greek mathematics and the major developments in Islamic mathematics are discussed fully in History of trigonometry and Mathematics in medieval Islam. The subject came to fruition in Early Modern times with important developments by John Napier, Jean Baptiste Joseph Delambre, Delambre and others, and attained an essentially complete form by the end of the nineteenth century with the publication of Todhunter's textbook ''Spherical trigonometry for the use of colleges and Schools''. Since then, significant developments have been the application of vector methods, quaternion m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
