«قَدْ طَلَبْنَا فَلَمْ نَجِدْ لَكَ فِي السُّؤْدَدِ وَالْمَجْدِ وَالْمَكَارِمِ مِثْلًا»
We searched, but found no peer of yours in nobility, honor, and excellence.
The object of the initial search is understandable from the rest of the praise. Leaving that part implicit allows the statement to advance quickly to its result, while the later «مثلا» explicitly identifies the standard of comparison.
Deletion and expression may both be purposeful within one utterance: ellipsis compresses the opening, and the later object names the claim of peerlessness. Neither operation is universally superior independent of context.
