فَأَمَّا الْيَتِيمَ فَلَا تَقْهَرْ
So, as for the orphan, do not oppress him. (الضحى: 9)
Fa-ammā marks the transition from remembered favor to practical instruction. Ammā isolates a topic and introduces its ruling. Al-yatīma is the fronted object-like topic in the construction, while lā taqhar contains prohibitive lā and a jussive imperfect.
The discourse moves from declarative report to directive speech: prior protection is followed by an instruction not to mistreat the orphan. That shift makes a simple “all clauses have the same speech act” description incorrect. Their coherence depends on the thematic relationship and communicative purpose.
