Health and medical perspectives on the prohibition of pork in Islam While pork is a widely consumed red meat, it differs significantly from ruminant meats (beef and lamb) in terms of the animal's digestive physiology, metabolic waste processing, and susceptibility to zoonotic pathogens. This article explores the biological traits of pigs and examines why certain scientific and health perspectives categorize pork as a higher-risk meat compared to cow and sheep products and gives the Islamic perspective as well.

The Primordial Origin: Cosmological Singularity and the Quranic Paradigm Modern physical cosmology posits that the universe originated from a singular point of infinite density and temperature, an event commonly known as the Big Bang. This article examines the convergence between contemporary astrophysical models—specifically the Friedmann-Lemaître-Robertson-Walker (FLRW) metric—and 7th-century Quranic descriptions of cosmic origins. By synthesizing perspectives from Western theoretical physicists and Islamic scholars, this paper explores the "Ratq" and "Fatq" (sewing and rending) concepts as early theological precursors to the concept of the Primordial Singularity and subsequent cosmic expansion.
