وَكَانَ طَوَى كَشْحًا عَلَى مُسْتَكِنَّةٍ ۞ فَلَا هُوَ أَبْدَاهَا وَلَمْ يَتَقَدَّمِ
He had folded away a secret purpose within himself; he neither disclosed it nor acted prematurely.
Ṭawā kashḥan, literally folding the flank, is an idiom for keeping an intention hidden. Mustakinnah denotes something concealed and settled within the heart. The suffix in abdāhā refers back to that secret matter. The verse separates outward silence from genuine reconciliation.
