On Theriac

Muhammad b. ‘Abd Allah al-Ajlah narrated from Safwan b. Yahya al-Bayya’ from ‘Abd al-Rahman b. al-Hajjaj, who said: A man asked Abu al-Hasan, peace be upon him, about theriac (al-tiryaq). He replied: “There is no objection to it.” He said: “O son of the Messenger of Allah, it contains the flesh of vipers (al-afa’i).” He [Abu al-Hasan] replied: “It has no power over us.”
