This is unrelated to bash, it's 100% ssh(1) behavior.

Anyway, I bet one of the default keys *is* in the authorized_keys
file for user ayoub. -i doesn't mean use this key _and only this_ The
default key such as ~/.ssh/id_rsa,  ~/.ssh/id_ecdsa, etc. are still
tried, as well as others available in the ssh-agent. Run ssh with some
-v to see what it is actually trying. Add -oIdentitiesOnly=yes to only
use the identities explicitly provided.
