How do we reconcile the Prophet's saying, peace and blessings be upon him, "Every innovation is misguidance," with the saying of some scholars that there are innovations whose ruling is detested?

Some scholars have used the term "disliked" (makruh (definition)) for certain innovations (bid'ah), and Al-Izz ibn Abd al-Salam categorized them into: obligatory, forbidden, recommended, disliked, and permissible.

However, others hold the view—and this is the more preponderant opinion—that all innovations are blameworthy, but they vary in their degree of prohibition. Some are disbelief (kufr), some are acts of disobedience (ma'siyah), and some are disliked.

The preponderant view is that when an innovation is described as "disliked," the correct understanding is that it refers to a prohibitive dislike (karahah tahrimiyyah), not a merely disliked dislike (karahah tanzihiyyah). Thus, every innovation in Islamic law is misguidance, though they differ in their degree. If it is said that an innovation is "good" based on legal evidence, then either it is not an innovation in religion, even if it is called an innovation linguistically, or this is a general rule from which this specific instance has been excluded due to a preponderant conflicting evidence.

Every innovation is misguidance and forbidden. There is no innovation that is merely disliked with a dislike of slight aversion (karahah tanzihiyyah). The dislike of slight aversion applies to prohibitions.
