«وَأَمَّا السَّائِلَ فَلَا تَنْهَرْ»
And as for the one who asks, do not rebuke him.
This verse parallels the preceding prohibition: ammā introduces a topic and the response uses fa followed by a prohibitive expression. Their correspondence gives separate weight to two duties.
Parallel construction does not automatically amount to jinās, which depends on a particular similarity of word forms with a difference in meaning. Here the evident effect is balanced structure and focused guidance.
