Not every Qur’anic ruling is presented at the same degree of detail. Sometimes one comprehensive expression states a duty, while another passage specifies a condition, legal boundary, or entitlement. This variation in brevity and detail serves the subject and intended purpose.
Ijmāl is a concise statement whose complete practical implementation is not contained in the immediate wording. Tafṣīl specifies conditions, distinctions, or applications. Interpretation should first ask what the verse states in context, and then identify the legitimate sources of further explanation. Neither concision nor detail should be ignored.
