The name alone does not satisfy Abū Zayd. He asks for more information, but wraps the request in a courteous blessing.
«زِدْنِي إِيضَاحًا، زَادَكَ اللَّهُ صَلَاحًا»
Tell me more clearly; may God increase you in goodness.
Zid is an imperative, while zāda is formally past tense; both come from the same root. The endings of īḍāḥ / ṣalāḥ create rhythmic prose. The past-tense form zādaka Allāhu is a conventional supplication, not a report that an event has already happened.
«عِشْتَ وَنَعِشْتَ»
May you live and be restored to well-being. The rhyming wishes are related, but the first concerns life and the second improvement.
