Which is more eloquent: Ahmad ibn Abdullah, or Ahmad Abdullah?

The first and more eloquent way is to say "Ahmad ibn Abdullah" instead of "Ahmad Abdullah," because what is customary in the Arabic language and the language of Sharia is to affirm the word "ibn" (son of) in lineage, both in pronunciation and writing. Its omission was unknown in the early days of Islam, nor in Islamic records, chronicles, or biographical works; rather, it originated from non-Arabs. Therefore, it should be said "Ahmad ibn Muhammad ibn Hassan" to avoid imitating non-Arabs.
