Biography of Islamic Scholar Abu'l Hasan Ahmad ibn Ibrahim Al-Uqlidisi

Assalamu Alaikum, sisters, brothers, friends and elders, we welcome you to a series of videos on Muslim heritage and Islamic scholars. and today in this video we will describe biography of Abu'l Hasan Ahmad ibn Ibrahim Al-Uqlidisi

Abu'l Hasan Ahmad ibn Ibrahim Al-Uqlidisi was a distinguished Muslim mathematician and scholar who lived during the tenth century. He is best known for his pioneering contributions to arithmetic and the development of decimal fractions. Although little is known about the intimate details of his personal life, his work has survived as a legacy that influenced generations of scholars in the fields of mathematics and science. He was born around the year 920 in Damascus, the heart of Syria, a city that was renowned for its scholarship, culture, and intellectual traditions during the golden age of Islam.

Al-Uqlidisi lived at a time when the Islamic world was flourishing with advancements in science, medicine, astronomy, and mathematics. Scholars of his era preserved and built upon the works of Greek, Indian, and Persian thinkers. The name Al-Uqlidisi itself suggests his association with the Greek mathematician Euclid, whose writings on geometry were widely studied in the Islamic world. However, Al-Uqlidisi distinguished himself not by geometry but by making arithmetic more practical and accessible for daily life and commerce.

His most notable work is the book “Kitab al-Fusul fi al-Hisab al-Hindi,” which translates as “The Book of Chapters on Hindu Arithmetic.” This book, written around 952, is considered one of the earliest surviving Arabic texts that thoroughly discusses Hindu-Arabic numerals and methods of calculation. Al-Uqlidisi emphasized the efficiency of using the decimal system, which was based on the numerals 0 to 9. While the numeral system had been introduced from India earlier, Al-Uqlidisi’s contribution was to simplify it and demonstrate its practical applications for merchants, accountants, and students.

One of his most significant achievements was the development of decimal fractions. Instead of relying solely on complex fractions and ratios, he showed how decimal fractions could be applied in arithmetic operations. This innovation was revolutionary because it provided an easier way of expressing numbers and performing calculations, laying the foundation for future progress in mathematics and science. His explanations of how to multiply and divide using decimals proved extremely valuable for both theoretical mathematics and everyday trade.

Al-Uqlidisi also discussed methods of calculation that could be carried out without a dust board, which was a common tool at the time. Most mathematicians used dust boards, or sand boards, to perform their calculations, but Al-Uqlidisi demonstrated techniques that allowed people to calculate with pen and paper instead. This practical advancement made arithmetic more widespread and accessible, especially for those who did not have access to traditional tools of scholars.

The exact date of Al-Uqlidisi’s death is uncertain, but historians suggest that he passed away around the year 980 in Damascus, where he had spent most of his life. Damascus, being one of the great centers of Islamic learning, was a fitting place for his contributions to be preserved and celebrated. His works continued to influence later scholars in both the Islamic world and Europe, especially during the translation movement when Arabic texts were rendered into Latin.

As for his shrine, it is believed that Al-Uqlidisi was buried in Damascus, although the precise location of his grave is not clearly documented. Damascus has long been home to the shrines of scholars, saints, and luminaries of Islamic history. The city’s cemeteries hold the resting places of many great figures, and Al-Uqlidisi is remembered among them as a man of knowledge and innovation. His name continues to be honored in the history of mathematics, even if his physical shrine is not widely visited like those of other famous saints or scholars.

In conclusion, Abu'l Hasan Ahmad ibn Ibrahim Al-Uqlidisi stands as a remarkable figure in Islamic intellectual history. Born in Damascus in 920, he lived through a golden era of learning and contributed lasting advancements to the science of arithmetic. His book on Hindu arithmetic and his introduction of decimal fractions paved the way for modern mathematics. He passed away in Damascus around 980, leaving behind a legacy that continues to inspire scholars and mathematicians across the world. Though his shrine remains modest and not prominently documented, his intellectual contributions remain a shining monument to his name.

With this, we ask for your permission until tomorrow and tomorrow we will narrate biography of . we will also narrate the history of her shrine. Finally, we pray to Allah Almighty to grant us the ability to act on the Quran and Hadith, Amen.
