Principle Twenty: The Qur’an is, from one perspective, wholly muhkam (decisive), from another wholly mutashabih (ambiguous/consistent), and from a third perspective some of it is muhkam and some of it is mutashabih.
Allah, exalted is He, has applied each of these three descriptions to His Book. He calls it muhkam in several verses, among them: “A Book whose verses have been perfected and then set forth in detail by One who is All-Wise, All-Aware” (Hud 11:1). This means that the Qur’an is perfected to the highest degree and flawlessly ordered: all of its reports are true and reliable, free of contradiction or disparity; all of its commands bring goodness, blessing, and reform; and all of its prohibitions relate only to evils, harms, base character, and corrupt deeds. That is the aspect of its being muhkam.
He likewise describes it as mutashabih in His statement: “Allah has sent down the finest discourse, a Book consistent (mutashabihan)” (al-Zumar 39:23). That is, the Qur’an resembles itself in beauty, truth, and rightness, presenting beneficial meanings that refine the intellect, purify the heart, and set affairs aright. Its wording is the finest wording, and its meanings are the finest meanings.
He also says: “In it are verses that are muhkam—they are the foundation of the Book—and others are mutashabih” (Āl ʿImrān 3:7). Thus He affirms that part of the Qur’an is of one type and part of another, and that those firmly grounded in knowledge refer the mutashabih back to the muhkam, so the whole becomes muhkam. They declare, “All of it is from our Lord” (Āl ʿImrān 3:7), meaning that whatever comes from Him cannot contain contradiction; any passage that seems ambiguous in one place is clarified by another that is decisive, whereby knowledge is attained and the difficulty removed.
This principle has many illustrations, including the previously mentioned texts affirming that He is capable of all things; that whatever Allah wills comes to pass and whatever He does not will cannot occur; and that He guides whom He wills and leads astray whom He wills.
If someone, therefore, should find this perplexing and imagine—contrary to wisdom—that His guidance or misguidance occurs arbitrarily, without any cause—
