We have no clear idea of the account of al‑Mada'ini. It is possible that it is the main source of al‑Baladhuri for Abu Mikhnaf, but al‑Baladhuri introduces his account with the collective qalu. However, this version does not refer to the variation from `Awana which Ibn al‑Kalbi has introduced into his account. Al‑Mada'ind is used as a source by Abu al‑Faraj for a report from al‑Qasim b. al‑Asbagh which has already been cited, and there are other reports from him which are not from Abu Mikhnaf. So clearly he used other material to supplement Abu Mikhnaf s account.
