His travels certainly took him to Egypt and Persia, as Russell suggests, but he almost certainly also travelled to Babylon, and some claim he travelled to India and Ethiopia. Certainly he was a man of great learning.
Kanyang travels tiyak kinuha siya sa Ehipto at Persiya, bilang Russell nagmumungkahi, ngunit siya halos tiyak din manlalakbay sa Babylon, at ilang mga claim siya manlalakbay sa Pilipinas at Ethiopia. Totoong siya ay isang tao ng mahusay na pag-aaral.
