4,000 or 40,000 stalls?

1 Kings 4:26—”Did Solomon have 40,000 stalls for his horses (1 Kings 4:26), or 4,000 stalls (2 Chronicles 9:25)?”

This is clearly a copyist mistake; the original text of both is 4,000. In Hebrew, forty (ארבעים) and four (ארבעת) look almost identical. This is no mistake with the original, merely a minor copying error by which a scribe encountered a smudged number. For a fuller explanation of such minor scribal copyist mistakes in the Qur’ān and Bible, see the see the article Minor Variants and Copying Errors in the Tawrat, Zabur, Injīl and Qur’ān.
