Abū l-Faḍl Ibn al-Qaysarānī (d. 507/1113) was a renowned transmitter of Prophetic traditions. He travelled the Islamic world, from Egypt to Khurāsān, in quest of ḥadīth, and he settled in Hamadhān. His edited works include books on ḥadīth and Qurʾānic studies and two Ṣūfī treatises. His fame as a ḥadīth transmitter was wide and solid, but some mediaeval traditionalists criticised him for belonging to the Ẓāhirī school of law and theology, for his permissive opinions about music and dance, and for his defence of Ṣūfī practices.
