«وَبَلَاغَةٍ رَائِعَةٍ وَبَدِيهَةٍ مُطَاوِعَةٍ وَآدَابٍ بَارِعَةٍ»
Remarkable eloquence, ready inventiveness, and distinguished literary skills.
Balāghah is effective, fitting expression. Badīhah muṭāwiʿah suggests the ready ability to respond aptly without lengthy preparation. Ādāb bāriʿah describes accomplished literary arts.
The additional phrase «وَقَدَمٍ لِأَعْلَامِ الْعُلُومِ فَارِعَةٍ» evokes his high standing across branches of learning. The sequence progresses from attractive presentation to eloquence, quick thinking, and breadth of learning. All are part of Abū Zayd's persuasive capacity.
