al-ʿArīfī vs. al-Maghāmisī

Two Saudi preachers, one orthodoxy, opposite instruments — the classical division of pulpit labor between warning and reassurance (الترهيب والترغيب), measured across 24 sermons and lectures.

The one-paragraph version. The hypothesis behind this pair was that two scholars of the same country, generation and creed would differ almost purely in delivery — and the data agrees, then sharpens it. Al-Arefe preaches the classical rhetoric of warning: admonition carries a third of his emotional weight, his pitch swings half again as wide as his counterpart's, and his sermons run on colloquial mini-dramas — staged everyday dialogues that pull the listener into the story. Al-Maghamsi teaches: calm instruction and reverence dominate, delivered in a narrower, steadier melodic band anchored in Quranic citation and liturgical formula. And beneath the opposite instruments, one identical engine: their linguistic certainty is statistically indistinguishable — same creed, different nervous system.

The division of pulpit labor

The gap-sorted comparison reads like a definition of الترهيب والترغيب. Admonition — hellfire, reckoning, consequence — belongs to al-Arefe (−18 pp). Calm instruction (+15 pp) and reverence (+7 pp) belong to al-Maghamsi. Urgency and indignation follow al-Arefe; grief, hope and exaltation lean al-Maghamsi. Per sentence, admonition dominates 18% of al-Arefe's talk against 4% of al-Maghamsi's.

A stylistic signature the palette almost missed: al-Arefe's "urgency" segments are largely storytelling — everyday dialogues in colloquial Gulf Arabic ("how much does he owe you? — ten riyals, wallahi ya rabbi"), staged as miniature moral dramas. Al-Maghamsi's corresponding segments cite scripture. Fear-drama versus scripture-calm, down to the sentence level.

The voice: half again as much melody

The vocal channel is where this pair was predicted to split, and it does: al-Arefe's median sermon moves through a 60 Hz pitch interquartile range against al-Maghamsi's 41 — and both dwarf every politician we have measured with the same instruments (17–25 Hz for Biden, Trump, Netanyahu, Lapid). Vocal arousal and dominance tell the same story twice: al-Arefe 0.79/0.75 vs al-Maghamsi 0.76/0.72 — high and higher. The pulpit out-projects the podium: the mosque register beats every political speaker on prosodic command (politicians: 0.48–0.62).

Same canon, same map

Semantically the two preach from one world: the clusters — God and His servants, the Prophet, human conditions and divine will — are shared territory, and message consistency across sermons is essentially identical (0.978 vs 0.980; sermon corpora are the most internally consistent genre we have measured, above even IDF war briefings). One structural difference: al-Arefe's openings are near-verbatim formula (similarity 0.90 vs 0.73) — the fixed khutba preamble — while al-Maghamsi varies his entries and instead standardizes his closings (0.79 vs 0.75).

Every sermon rises at the end

Emotional arcs show a genre law rather than a personal signature: both canonical shapes end with a sharp climb in the final tenth — the closing duʿāʾ, where warning resolves into supplication and glad tidings. The two preachers distribute nearly evenly across both shapes: the arc belongs to the liturgy; the voice inside it belongs to the man.
