دلالة النص: ما ثبت بعلة النص لغة لا اجتهاداً.
Dalalat al-nass is a ruling established through the text’s underlying rationale as understood linguistically, not through a separate act of legal ijtihad.
The phrase lughatan la ijtihadan is decisive: the relevant reason is apparent from the language and context, rather than being derived through an independent analogy.
A prohibition expressed through a relatively slight harmful act may linguistically indicate a fortiori prohibition of more harmful acts involving the same rationale.
