How do I deal with the intrusive thoughts and questions that have come to my mind since I embraced Islam, especially concerning the source of codified Fiqh and the reasons why jurists compiled it, and why the Companions did not compile in this regard? Am I obligated to seek out scholars to ask them about these details, or is it better to ignore them? And would I be sinful if I neglected to ask about them, while Allah has commanded it in His saying: "So ask the people of the message if you do not know"?

The codification of human sciences, including Fiqh (Islamic jurisprudence), goes through natural stages, as ideas begin with oral transmission, then initial concise codification, leading eventually to detailed branching and systematization. The codification of Fiqh began during the era of the Companions with some scattered scrolls that collected various rulings, then it developed further in the compilations of the Tabi'un (Successors) and their followers. Being the most knowledgeable (al-a'lamiyyah) is not necessarily linked to authorship, as early scholars focused on teaching and spreading awareness at a time when writing was of limited circulation. It is advisable to consult specialized references to understand the history and development of sciences.
