(a) It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) forbade that the imam should be the muezzin. This hadith is weak in its chain.
(b) Isma'il bin Amr al-Kufi narrated these hadiths, but he has no corroboration (mutaba'ah) in them, and Ja'far bin Ziyad is da'if (weak).
