Generated from a table of word-by-word decisions, not written as prose. Arabic word order is preserved, so it reads stiffly and is not a substitute for a translation written by a person. Every verse is rendered, but the whole remains under review: words marked as judgement rest on weaker evidence than the rest and are flagged in place. No tafsir, hadith or existing translation was consulted.
