The Obligation of Adhering to a Single Madhhab in all its Rulings

If the obligation of a non-mujtahid is only to follow, or make taqlid, of qualified mujtahids, why do scholars insist on the added obligation of restricting one’s taqlid to a single madhhab?

The paper linked below addresses this question, providing a detailed explanation for the necessity of adhering to a single madhhab in all its rulings.

The obligation and its legal basis are supported by statements and opinions from major early authorities across the recognised schools of jurisprudence. It is argued that this ruling is not only more sound in the present context, but is also supported by strong positions from within each of the four madhhabs, with some of the early scholars having quoted consensus.
