Tabular Islamic Calendar
The Tabular Islamic calendar ( ar, التقويم الهجري المجدول, altaqwim alhijriu almujadwal) is a rule-based variation of the Islamic calendar. It has the same numbering of years and months, but the months are determined by arithmetical rules rather than by observation or astronomical calculations. It was developed by early Muslim astronomers of the second hijra century (the 8th century of the Common Era) to provide a predictable time base for calculating the positions of the moon, sun, and planets. It is now used by historians to convert an Islamic date into a Western calendar when no other information (like the day of the week) is available. Its calendar era is the Hijri year. An example is the Fatimid or Misri calendar. It is used by some Muslims in everyday life, particularly in Ismaili and Shi'a communities, believing that this calendar was developed by Ali. It is believed that when Ali drew up this calendar, the previous events of the earlier prophets also f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kūshyār Ibn Labbān
Abul-Hasan Kūshyār ibn Labbān ibn Bashahri Daylami (971–1029), also known as Kūshyār Daylami ( fa, کوشیار دیلمی), was an Iranian mathematician, geographer, and astronomer from Daylam, south of the Caspian Sea, Iran. Career His main work was probably done about the beginning of the eleventh century, and seems to have taken an important part in the elaboration of trigonometry. For example, he continued the investigations of Abul Wáfa, and devoted much space to this in his zij (or collection of tables) ''az-Zīj al-Jamī wal-Baligh'' ("the comprehensive and mature tables"), which incorporated the improved values of the planetary apogees observed by al-Battani.E. S. Kennedy, ''A Survey of Islamic Astronomical Tables,'' (Transactions of the American Philosophical Society, New Series, 46, 2), Philadelphia, 1956, pp. 3, 34-5. The tables were translated into Persian before the end of the century. He wrote also an astrological introduction and an arithmetic treatise ''Ki ...

Dawoodi Bohras
The Dawoodi Bohras are a religious denomination within the Ismā'īlī branch of Shia Islam. Their largest numbers reside in India, Pakistan, Yemen, East Africa, and the Middle East, with a growing presence across Europe, North America, South East Asia, and Australia. Most estimates put the worldwide population to be one million. The Dawoodi Bohras are known to be a close-knit community who, like all Muslims, follow the tenets of Islam; namely reciting the Quran, observing the five daily prayers, fasting during the month of Ramadan, performing the pilgrimages of Hajj and Umra and offering Zakat. Whilst adherence to traditional values is important for the community, they are also known for their mercantilism and having a modernist approach to their lifestyles. The cultural heritage of this denomination is found in the traditions of the Fatimid Imams; direct descendants of the Islamic prophet Muhammad through his daughter Fatima. The Fatimids ruled over North Africa between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dutch East Indies
The Dutch East Indies, also known as the Netherlands East Indies ( nl, Nederlands(ch)-Indië; ), was a Dutch colony consisting of what is now Indonesia. It was formed from the nationalised trading posts of the Dutch East India Company, which came under the administration of the Dutch government in 1800. During the 19th century, the Dutch possessions and hegemony expanded, reaching the greatest territorial extent in the early 20th century. The Dutch East Indies was one of the most valuable colonies under European rule, and contributed to Dutch global prominence in spice and cash crop trade in the 19th to early 20th centuries. The colonial social order was based on rigid racial and social structures with a Dutch elite living separate from but linked to their native subjects. The term ''Indonesia'' came into use for the geographical location after 1880. In the early 20th century, local intellectuals began developing the concept of Indonesia as a nation state, and set the stage ...

Al-Bīrūnī
Abu Rayhan Muhammad ibn Ahmad al-Biruni (973 – after 1050) commonly known as al-Biruni, was a Khwarazmian Iranian in scholar and polymath during the Islamic Golden Age. He has been called variously the "founder of Indology", "Father of Comparative Religion", "Father of modern geodesy", and the first anthropologist. Al-Biruni was well versed in physics, mathematics, astronomy, and natural sciences, and also distinguished himself as a historian, chronologist, and linguist. He studied almost all the sciences of his day and was rewarded abundantly for his tireless research in many fields of knowledge. Royalty and other powerful elements in society funded Al-Biruni's research and sought him out with specific projects in mind. Influential in his own right, Al-Biruni was himself influenced by the scholars of other nations, such as the Greeks, from whom he took inspiration when he turned to the study of philosophy. A gifted linguist, he was conversant in Khwarezmian, Persian, Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ibn Al-Ajdābī
Ibn al-Ajdābī ( ar, أبو إسحاق إبراهيم بن إسماعيل بن أحمد بن عبد الله اللواتي الأجدابي الطرابلسي, Abū Ishāq Ibrāhīm ibn Ismā'īl ibn Ahmad ibn Abdallāh al-Lawātī al-Ajdābī al-Tarāblisī) died after c. 1077 AD (456 AH) was a prominent Libyan scholar and linguist. His fields of expertise covered Islamic jurisprudence, kalam, Arabic language and astronomy. He lived all his life in Tripoli and died and was buried there. He studied under Libyan scholars of his time and was famous for being interested in meeting those who traveled through Tripoli from the Mashriq and the Maghrib and acquiring wider knowledge from them. It is said that when he was asked about how he acquired all this knowledge, he replied, "I acquired it from the Huwwāra and Znāta gates," which refers to the names of two main gates to Tripoli, named after two Berber tribes.

Taiyabi Ismaili
Tayyibi Isma'ilism is the only surviving sect of the Musta'li branch of Isma'ilism, the other being the extinct Hafizi branch. Followers of Tayyibi Isma'ilism are found in various Bohra communities: Dawoodi, Sulaymani, and Alavi. The Tayyibi originally split from the Fatimid Caliphate-supporting Hafizi branch by supporting the right of at-Tayyib Abu'l-Qasim to the Imamate. History Upon the death of the twentieth Imam, al-Amir bi-Ahkam Allah (d. ), his two-year-old child at-Tayyib Abu'l-Qasim (b. ) was appointed the twenty-first Imam. As he was not in a position to run the Dawah, Queen Arwa al-Sulayhi, the Da'i al-Mutlaq, acted as his regent. The Da'i had now been given absolute authority and made independent from political activity. Da'i Zoeb bin Moosa Da'i Zoeb bin Moosa used to live in and died in Hoos, Yemen. His ''ma'zoon'' ("associate") was Khattab bin Hasan. After death of Abdullah, Zoeb bin Moosa appointed Yaqub as the wali ("representative" or "caretaker") of the T ...

Toledan Tables
The ''Toledan Tables'', or ''Tables of Toledo'', were astronomical tables which were used to predict the movements of the Sun, Moon and planets relative to the fixed stars. They were a collection of mathematic tables that describe different aspects of the cosmos including prediction of calendar dates, times of cosmic events, and cosmic motion. Origins The Toledan Tables were completed around 1080 by a group of Arabic astronomers at Toledo, Spain. They had started as preexisting Arabic tables made elsewhere, and were numerically adjusted to be centered on the location of Toledo. The Tables of Toledo were partly based on the work of al-Zarqali (known to the West as Arzachel), an Arab mathematician, astronomer, astronomy instrument-maker, and astrologer, who lived in Toledo. The tables were produced by a team whose membership is largely unknown, with the exception of al-Zarqali. Toledo came under Christian Spanish rule in the mid-1080s, shortly after the tables were completed. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Al-Battānī
Abū ʿAbd Allāh Muḥammad ibn Jābir ibn Sinān al-Raqqī al-Ḥarrānī aṣ-Ṣābiʾ al-Battānī ( ar, محمد بن جابر بن سنان البتاني) ( Latinized as Albategnius, Albategni or Albatenius) (c. 858 – 929) was an astronomer and mathematician from Harran. He introduced a number of trigonometric relations, and his ''Kitāb az-Zīj'' was frequently quoted by many medieval astronomers, including Copernicus. Often called the "Ptolemy of the Arabs", al-Battani is perhaps one of the greatest and best known astronomer of the medieval Islamic world. Life Little of al-Battānī's life is known other than his birthplace in Harran near Urfa, in Upper Mesopotamia, (today in Turkey) and his father's fame as a maker of scientific instruments. Jabir ibn Sinan al-Harrani was likely this famous instrument maker, although this is not something that has been proven. His epithet ''aṣ-Ṣabi’'' suggests that his family belonged to the Sabian religion of Harran, an obscur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
