Abū ‘Alī al-Ḥusayn ibn ‘Abd Allāh ibn Sīnā', known as Abū Alī Sīnā
(Persian: ابوعلی سینا) or, more commonly, Ibn Sīnā[4] (Arabic: ابن سینابلخي‎), but most commonly known in English by his Latinized name Avicenna (Greek: Aβιτζιανός, Abitzianos),[5] (c. 980 - 1037) was a Persian[6] polymath and the foremost physician and philosopher of his time.[7] He was also an astronomer, chemist, geologist, Hafiz, Islamic psychologist, Islamic scholar, Islamic theologian, logician, paleontologist, mathematician, Maktab teacher, physicist, poet, and scientist.[8]



Ibn Khaldūn or Ibn Khaldoun (full name, Arabic: أبو زيد عبد الرحمن بن محمد بن خلدون الحضرمي ‎, Abū Zayd ‘Abdu r-Raḥman bin Muḥammad bin Khaldūn Al-Hadrami, (May 27, 1332 AD/732 AH – March 19, 1406 AD/808 AH) was an Arab polymath[1][2] — an astronomer, economist, historian, Islamic jurist, Islamic lawyer, Islamic scholar, Islamic theologian, hafiz, mathematician, military strategist, nutritionist, philosopher, social scientist and statesman—born in North Africa in present-day Tunisia.[3] He is considered a forerunner of several social scientific disciplines: demography,[4] cultural history,[5][6] historiography,[7][8][9] the philosophy of history,[10] and sociology.[4][8][9][10][11][12] He is also considered one of the forerunners of modern economics,[8][13][14] alongside the earlier Indian scholar Chanakya.[15][16][17][18] Ibn Khaldun is considered by many to be the father of a number of these disciplines, and of social sciences in general,[19][20] for anticipating many elements of these disciplines centuries before they were founded in the West. He is best known for his Muqaddimah (known as Prolegomenon in English), the first volume of his book on universal history, Kitab al-Ibar.


Abu Abdullah Muhammad Ibn Abdullah Al Lawati Al Tanji Ibn Battuta Arabic: أبو عبد الله محمد ابن عبد الله اللواتي الطنجي بن بطوطة‎ or simply Ibn Battuta (February 24, 1304–1368 or 1369) was a Moroccan Berber Muslim scholar and traveller who is known for the account of his travels and excursions called the Rihla (Voyage) in Arabic. His journeys lasted for a period of nearly thirty years and covered almost the entirety of the known Islamic world and beyond, extending from North Africa, West Africa, Southern Europe and Eastern Europe in the West, to the Middle East, Indian subcontinent, Central Asia, Southeast Asia and China in the East, a distance readily surpassing that of his predecessors and his near-contemporary Marco Polo. With this extensive account of his journey, Ibn Battuta is often considered as one of the greatest travellers ever.[1]
