← Claims & Evidence

Is the call to reason unique to the Qur'an? — an honest comparison with earlier scriptures

The claim comes from two directions: some say "the Qur'an is hostile to reason"; others, conversely, say "the Qur'an's emphasis on reason isn't original — it was borrowed." Let us weigh both from the sources, hiding nothing.

1) Honesty first: the theme is present in earlier scriptures too

We do not conceal it. The Hebrew scriptures also issue a strong call to reason and understanding:

  • "O fools, when will ye be wise?" (Psalm 94:8) — and the Arabic (Van Dyck) renders it with the very root "متى تعقلون".
  • "Be not as the horse or mule, which have no understanding" (Psalm 32:9); "The ox knoweth his owner... but my people doth not consider" (Isaiah 1:3).
  • "Eyes, and see not; ears, and hear not" (Jeremiah 5:21; Ezekiel 12:2).

So the images of "likening the unreasoning to beasts" and "having senses yet not grasping" are a shared prophetic heritage.

2) What is distinctive in the Qur'an: frequency and centrality

The difference is not the theme's existence but its intensity and structural centrality. By commonly cited word-counts, in the Qur'an:

  • the verb "to reason" (ʿaql) occurs dozens of times (~49); the refrain "will you not use reason?" (afalā taʿqilūn) ~13 times (e.g. 2:44; 36:62).
  • "to reflect" (tafakkur) ~18 times; "people of understanding" (ulū al-albāb) ~16 times.
  • Failing to reason draws the gravest description: "the worst of creatures before God are those who do not reason" (8:22); "they are like cattle — nay, more astray" (7:179; 25:44; 2:171).

Here reason becomes not an occasional rebuke but a recurring, defining criterion of faith.

3) "A copy"? The Qur'an states the continuity openly

The Qur'an does not hide this commonality; it itself references the previous revelation:

  • "We ordained for them therein a life for a life, an eye for an eye..." (Q 5:45) ↔ Exodus 21:24.
  • "We wrote in the Zabūr: the land is inherited by My righteous servants" (Q 21:105) ↔ Psalm 37:29.
  • "We decreed for the Children of Israel: whoever kills a soul... as if he killed all mankind" (Q 5:32) ↔ Mishnah, Sanhedrin 4:5.
  • "Their likeness in the Gospel is as a seed that sends forth its shoot" (Q 48:29) ↔ Mark 4:28.

The continuity is stated within the text itself — not a hidden copy but an open claim of resting on the same source.

4) An honest limit (and counter-reading)

  • The theme is shared — it is wrong to present it as "found only in the Qur'an"; the Psalms and Proverbs also praise understanding.
  • What is distinctive is the frequency and systematic character of the emphasis — not that earlier scriptures disregarded reason.
  • Counter-reading, honestly: frequency alone is not a "proof of superiority." The finding here is a difference of emphasis — an observable pattern, not a rhetorical victory.
