The biographical notice places al-Nasafī among the teachers of the author of al-Hidāyah, the well-known Hanafi legal work. This situates him within a recognizable network of scholarly teaching.

A historical connection should not be converted into a proof of every doctrine or legal opinion. Such positions still require their appropriate scholarly arguments.
