Why does a certain jurisprudential opinion contradict the consensus of the four schools of thought and the majority of scholars regarding the permissibility of buying and selling cats, relying solely on one opinion (that of the Zahiri school) which prohibits it? Is the money generated from their sale lawful or dubious?

"Evidence must be followed when it appears, and there is no excuse for one who follows a saying while knowing that the evidence contradicts it. This falls under the condemnation mentioned in His Almighty's saying: {They have taken their scholars and monks as lords instead of Allah}. The majority of scholars have gone to the permissibility of selling cats, while some scholars have gone to its prohibition. This latter opinion is the preponderant one, supported by the hadith, and a group of verifiers have inclined towards it. There is no consensus on the permissibility of selling cats; rather, scholars have differed on this issue. Exiting from dispute by taking the more cautious approach is desirable. Money resulting from selling cats is unlawful according to the opinion of prohibition, but for one who trades in them, imitating those who permit it, there is no blame upon him."
