The question/claim: "The Qur'an declares pork and certain foods 'forbidden' without giving any rational reason. It never explains why; it just says 'forbidden.' Isn't this an arbitrary, random set of food taboos?"
Context
The Qur'an lists food prohibitions as four items, and this list recurs in almost identical wording: carrion (mayta), blood, pork, and animals slaughtered in a name other than God's (2:173; 5:3; 6:145; 16:115). For pork specifically, 6:145 adds the label "rijs" (filth).
A structural point matters: the prohibition verses usually follow immediately after a permission verse. In 2:172 the reader is told, "eat of the good things We have provided"; only in 173 are the exceptions listed. Likewise 16:114 commands eating lawful, wholesome provision, and 16:115 restricts it to the four bans. So the text's framing is not "everything is forbidden, a few things allowed" but the reverse: everything is basically lawful, a few things are exceptions.
Two readings
Classical fiqh and tafsir (Qurtubi, al-Jami' li-Ahkam al-Qur'an; the Diyanet commentary on 2:173 / 16:114-117; the Sorularlaislamiyet line) stress that the ban is bounded and specific, not arbitrary. A foundational principle of classical usul is "ibaha in things": something is lawful unless stated otherwise; the phrase in 6:145, "I do not find anything forbidden... except these," shows the forbidden is the exception (interpretation). On this view the ban's real basis is "ta'abbudi" — obedience to God's command and a test of servitude; a health harm may be a hikma (wisdom) but is not the sole rationale: "Even if pork's harms were fully removed today, the ban would remain" (interpretation). The necessity exception is also a fixed rule (al-daruratu tubihu al-mahzurat / الضرورات تبيح المحظورات): in a life-threatening emergency, without craving or excess, eating just enough to survive is lawful (2:173; 5:3; 6:145; 16:115).
A Qur'an-centric / academic reading (Mehmet Okuyan, kuranokuyan.com, on 2:173) turns the "arbitrary/unlimited ban" claim on its head. It notes that "innama" (إنّما) in the verse carries a restrictive force: God has forbidden "only" these four; the list is closed and narrowed (interpretation). This reading centers 5:87: "O you who believe, do not forbid the good things God has made lawful for you, and do not transgress; God does not love transgressors." On this view the real danger of arbitrariness lies in people declaring forbidden what God made lawful — and that is precisely what the Qur'an criticizes (interpretation).
Honest limit
The fair part of the objection: the Qur'an does not give an explicit rational/medical reason for the pork ban within the text. It says only "it is forbidden" and "rijs/filth" (6:145); there is no "it transmits such-and-such disease." To an outside observer this is a command whose reason is unstated; the criticism "the rationale isn't explicit in the text" is understandable in that sense.
But two meanings must not be conflated. If "arbitrary" means unlimited/random, the claim is false: the list is explicitly capped at four items and there is a necessity exception. If it means "the rationale isn't explicit in the text," it is partly true.
Certain in the text: the prohibitions themselves (2:173; 5:3; 6:145; 16:115), the "rijs" label for pork (6:145), and the necessity license. Disputed at the level of interpretation: the why. Popular apologetic arguments repeated in circulation — "suoxin," "the pig doesn't clean itself," the trichinella emphasis — are academically weak or inconsistent (many harmful agents occur in other meats too; "suoxin" has no scientific basis). An anthropological alternative (the Marvin Harris line) ties the ban to an ecological logic: in arid regions the pig is inefficient in water and feed (interpretation). None of these appear in the Qur'anic wording; all are reasons produced afterward. Whether "rijs" denotes health or ritual impurity is likewise interpretation.
