Furthermore, a simple study of al-Kulaynī’s teachers shows that most of them were Qummīs and only a negligible number of them were actually from Baghdād. The fact that he starts his work with traditions about the intellect and the importance of knowledge, or that he does not narrate many of the traditions on Imāmah that al-Ṣaffār does is because, unlike the simplistic categorization of Baghdād and Qum as centres of rationalism and traditionalism respectively, Qum actually did have rationalistic trends as well. Additionally, al-Kulaynī himself states in the introduction to al-Kāfī, that he intended to write a book on Imāmah, and that is where he most likely intended to compile a more complete set of traditions on the subject. Aside from this, in the instances where al-Sadūq narrates from al-Kulaynī, he does so through a chain comprising of narrators from Ray, thereby showing that al-Kāfī attained popularity in Ray before it did in Baghdād.
