He was a descendant of Abdallah Ibn Masu’d RA, a companion of the Holy Prophet (peace be upon him). An expert geographer, a physicist and historian, Masu’di was born in the last decade of the 9th century C.E., his exact date of birth being unknown. He explored distant lands and died at Cairo, in 957 C.E.

He travelled to Fars in 915 C.E. and, after staying for one year in Istikhar, he proceeded via Baghdad to India, where he visited Multan and Mansoora before returning to Fars. From there he travelled to Kirman and then again to India. Mansoora in those days was a city of great renown and was the capital of the Muslim state of Sind. Around it, there were many settlements/townships of new reverts to Islam. In 918 C.E., Masu’di travelled to Gujrat, where more than 10,000 Arab Muslims had settled in the sea-port of Chamoor. He also travelled to Deccan, Ceylon, Indo-China and China, and proceeded via Madagascar, Zanjibar and Oman to Basra.

At Basra he completed his book Muruj-al-Thahab, in which he has described in a most absorbing manner his experience of various countries, peoples and climates. He gives accounts of his personal contacts with the Jews, Iranians, Indians and Christians. From Basra he moved to Syria and from there to Cairo, where he wrote his second extensive book Muruj al-Zaman in thirty volumes. In this book he has described in detail the geography and history of the countries that he had visited. His first book was completed in 947 C.E. He also prepared a supplement, called Kitab al-Ausat, in which he has compiled historical events chronologically. In 957 C.E., the year of his death, he completed his last book Kitab al-Tanbih wa al-Ishraf, in which he has given a summary of his earlier book as well as an errata.

Masu’di is referred to as the Herodotus and Pliny of the Arabs. By presenting a critical account of historical events, he initiated a change in the art of historical writing, introducing the elements of analysis, reflection and criticism, which was later on further improved by Ibn Khaldun. In particular, in al-Tanbeeh he makes a systematic study of history against a perspective of geography, sociology, anthropology and ecology. Masu’di had a deep insight into the causes of rise and fall of nations.

With his scientific and analytical approach he has given an account of the causes of the earthquake of 955 C.E., as well as the discussions of the water of the Red Sea and other problems in the earth sciences. He is the first author to make mention of windmills, which were invented by the Muslims of Sijistan.

Some doubts have been expressed about some claims related to his extensive travelling e.g., up to China and Madagascar, but the correct situation cannot be assessed due to the loss of his several books. Whatever he has recorded was with a scientific approach and constituted an important contribution to geography, history and earth sciences. His researches and views extensively influenced the sciences of historiography, geography and earth sciences for several countries.
