Surah 98:6–7:
Indeed, those who disbelieved among the People of the Scripture and the polytheists will be in the fire of Hell, abiding eternally therein. Those are the worst of creatures. Indeed, those who have believed and done righteous deeds—those are the best of creatures.
The primary sociological impact of Surah 98 is its aggressive, absolute dehumanization of outgroup communities, explicitly categorizing Jews, Christians, and polytheists who reject Muhammad as "sharru al-bariyyah"—the worst of all created things.
The Behavioral Transition: In early Meccan passages, the text generally treats Jewish and Christian scriptures with immense deference, appealing to them as elder monotheistic authorities to validate Muhammad's claims. However, as the movement scales and demands exclusive political sovereignty, the tone hardens into zero-sum hostility.
The Sociological Inversion: The text establishes a rigid psychological caste system:
OUTGROUP: SHARRU AL-BARIYYAH
INGROUP: KHAYRU AL-BARIYYAH
To a sociologist or behavioral analyst, this absolute polarization ("Worst of Creatures" vs. "Best of Creatures", v. 6–7) is a classic mechanism of high-control sectarian conditioning. It systematically strips away the shared human dignity of neighbors, family members, and trading partners who held legitimate intellectual or traditional objections to Muhammad's authority. By painting outgroup members not merely as mistaken, but as biologically or structurally corrupted entities lower than animals, the text provides the psychological greenlight necessary for the military expansion, subjection, and taxation of non-Muslims.
