Birth Place:	Sarakhs
Death Date:	899 CE
Nationality:	Persian
Occupation:	Traveler, Historian, Philosopher

Ahmad ibn al-Tayyib al-Sarakhsi (Persian: أحمد بن الطيب السرخسي; died 899 CE) was a Persian^[1] traveler, historian and philosopher from the city of Sarakhs. He was a pupil of al-Kindi.^[2]

Al-Sarakhsi was killed by Caliph al-Mu'tadid because, according to an anecdote preserved in Yaqut al-Hamawi's Mu'jam al-Udaba, he had urged the caliph towards apostasy. Al-Biruni reports in his Chronology that al-Sarakhsi had written books in which he denounced prophecy and ridiculed the prophets, whom he styled charlatans. However, Rosenthal has disputed the historicity of the stories that claim al-Sarakhsi was executed for heretical beliefs.^[3]
