Is it permissible for a student of knowledge or a layperson to deem one of the sayings of scholars as anomalous (shādhdh) due to its contradiction of explicit evidence, and when is a saying deemed anomalous?

The anomalous view (al-qawl al-shadhdh) among jurists refers to what contradicts the view of the majority (jumhur) or the consensus (ijma'), or what deviates from the established principle (qa'idah) and analogy (qiyas), or what its proponent contradicted from the views of other jurists.

In the terminology of the Hanafis and Malikis, it is the less preferred (marjuh), weak (da'if), or uncommon (gharib) opinion, as opposed to the well-known (mashhur), the preferred (rajih), or the sound (sahih) opinion.

A ruling on the anomalous nature of a view can only be made by a qualified scholar knowledgeable of the various views, their evidences, their probative force, and the methodology of preferring one over another.
