Alberuni (also spelled Al-Biruni) wrote the famous work Kitab-ul-Hind, also known as Tahqiq-i-Hind. Alberuni was a Persian scholar who visited India in the early 11th century, during the reign of Mahmud of Ghazni. His work provides a detailed account of Indian society, culture, religion, science, and mathematics of that time.
Kitab-ul-Hind is regarded as one of the most comprehensive and accurate accounts of Indian civilization written by a foreign scholar. Alberuni’s descriptions of Hinduism, Indian philosophy, astronomy, and mathematics are invaluable to historians and scholars.
He was known for his objective and analytical approach, making Kitab-ul-Hind an essential reference for understanding medieval India.
