فَلْيَضْحَكُوا قَلِيلًا وَلْيَبْكُوا كَثِيرًا
Let them laugh little and weep much.
The pairs “laugh/weep” and “little/much” form an ordered double opposition, marking the structure of muqābalah. A single contrary pair can suffice for ṭibāq.
The examiner should locate the mapped pairs instead of merely asserting that opposites exist.
