Surah 68:10–14:
And do not obey every worthless swearer—A scorner, going about with malicious gossip—A preventer of good, transgressing and sinful, cruel, and moreover, an illegitimate child because he is a possessor of wealth and children.
Instead of answering the intellectual or theological skepticism of the Meccan elders with reasoned arguments, the text unleashes an intensely personal, ad-hoc character assassination against a specific, living tribal opponent (historically identified as Al-Walid ibn al-Mughirah, a wealthy Meccan chief).
Verses 10–14 demand that Muhammad ignore this critic, describing him using a rapid succession of severe social slurs:
"A worthless swearer" (ḥallāfin mahīn - v. 10)
"A scorner, going about with malicious gossip" (hammaāzin mashshāʾin bi-namīm - v. 11)
"Cruel, and moreover, an illegitimate child/bastard" (ʿutullin baʿda dhālika zanīm - v. 13)
To an ethical philosopher or sociologist, the use of the word Zanīm (explicitly meaning a bastard, a person falsely adopted into a lineage, or a social parasite) represents a highly provincial, tribal insult rooted entirely in 7th-century Arab bloodline mechanics.
The text abandons cosmic, universal guidance to engage in a gutter-level street brawl, weaponizing a person’s alleged illegitimacy to invalidate their philosophical skepticism. It reduces divine revelation to a vehicle for localized, personal score-settling.
