What is your advice to someone who adheres to the Madhhab of Abu Hanifa, but takes rulings from other Madhhabs due to the unavailability of an a knowledgeable scholar (mujtahid) in his own Madhhab, and wishes to avoid mixing between Madhhabs?

A Muslim must act in accordance with the Book of Allah and the Sunnah of His Prophet. He is not obligated to follow a specific school of thought among the four Sunni schools, and it is not permissible for him to perform an action that contradicts the established evidence he possesses, under the pretext that it is the madhhab he emulates.
