الصريح لفظ يكون المراد به ظاهراً
An explicit expression is one whose intended meaning is apparent.
An expression is apparent when its established use communicates the relevant sense without requiring investigation of a concealed intention. “Biʿtu” (“I sold”) and “ishtaraytu” (“I purchased”) illustrate direct contractual language.
Ṣarīḥ is not restricted to one grammatical construction. The controlling feature is whether the operative meaning is plainly expressed in the setting in which the words are used.
