Ahmed Bin Jaafar Bin Brahim Ibn Al Jazzar Al-Qayrawani (895 – 979) (Arabic: أبو جعفر أحمد بن أبي خالد بن الجزار القيرواني‎‎), was an influential 10th-century Muslim physician who became famous for his writings on Islamic medicine. He was born in Qayrawan in modern-day Tunisia. He was known in Europe by the Latinized name Algizar.

We know the biography of Ibn Al Jazzar only by an Andalusian physician Ibn Juljul and he only knew it by his student Ibn Bariq, who went to Qayrawan, Tunisia to learn medicine. The writers of Tabakates or "classes of famous men" generally considered writing only for Faquih, the benefactors and the saints. The information we have about Ibn Al Jazzar are second hand, they are either incomplete, or controversial.

“Ahmed Ben Jaafar Ben Brahim Ibn Al Jazzar” was born in Qayrawan around 895, and died around 979. He lived about 84 years. Married he would not let childs. He had learned the Koran at kuttab in his youth, grammar, theology, fiqh and history at the mosque Okba Ibn Nafaa. He had learned medicine from his father and his uncle that were physicians, and from Ishaq Ibn Suleiman (Isaac Ben Salomon), a physician in Qayrawan.

The existence of a hospital in Kairouan is not proven. Teaching is provided by the doctors themselves at home. This is the case of Ibn Al Jazzar. He said himself in the conclusion of his book "Zad Al Mussafir (viaticum), he would be available at home for his students at the end of its daily consultation.

The teaching was oral. The paper was not widely spread in the ninth century, the scrolls were rare and expensive. Ibn Al Jazzar had a library rich of 25 quintals, as it seems. This figure seems exaggerated. The quintal at the time amounted to 50 kg according to some and 25 kg according to others. These books were not all about medicine, but also of other disciplines.

Ibn Al Jazzar was calm and quiet. He did not attend funerals or weddings, and did not take part in festivities. He had great respect for himself. He avoided compromises, did not attend the court and members of the regime, thus taking on Fouqaha example of the time. This may explain the fact that when he treated the son of Cadhi Al Nooman, he refused to receive as a gift a costume of 300 mithkals. It is also by respect of the Emir that he had not realized his desire to visit Andalusia, the relationship between the two governments of Mahdia and Cordoba were tense. It is also by respect for the Emir that he did not begin his pilgrimage to Mecca in spite of his strong desire to do so. The Emir was Shia and for ceremonial purposes and policies, he creates barriers to pilgrims and forced them to pass through Mahdia and pay a toll.
