النص العربي
المقتطف
فالقياس الصحيح مثل أن يكون العلة التي علق بها الحكم في الأصل موجودة في الفرع من غير معارض في الفرع يمنع حكمها ومثل هذا القياس لا تأتي الشريعة بخلافه قط. وكذلك القياس بإلغاء الفارق وهو: أن لا يكون بين الصورتين فرق مؤثر في الشرع فمثل هذا القياس لا تأتي الشريعة بخلافه.

Selected explanation
Sound analogy is, for example, when the effective cause on which the ruling in the original case depends is present in the new case, without any countervailing factor in the new case that prevents that cause from producing its ruling. The revealed law never comes in opposition to an analogy of this kind. The same applies to analogy by eliminating any relevant difference: that is, there is no difference between the two cases that has an effect under the revealed law. The revealed law does not come in opposition to an analogy of this kind.
