اخْتِلَافُ الشَّرَائِعِ كَاخْتِلَافِ وَصَفَاتِ الطَّبِيبِ
Differences among dispensations resemble differences in a physician’s prescriptions.
Differences in some legal prescriptions are compared with a physician’s differing treatments. One patient may need warm nourishment, another cold; even the same patient’s instructions can change during recovery. The physician’s aim—to cure—remains constant.
The parallel is that prophetic guidance seeks to correct belief, character and practice. Different means may serve one stable purpose.
The analogy has limits: medical judgment does not independently establish a religious ruling. It only answers the conceptual objection that any difference in practical guidance must mean contradiction. Specific abrogation or obligation still needs authoritative evidence.
