It is narrated from Sayyiduna Jabir bin Samurah (may Allah be pleased with him) that Sayyiduna Bilal (may Allah be pleased with him) used to call the adhan after the sun had passed its zenith, and he would not call the iqamah until the Messenger of Allah (peace and blessings be upon him) came out. When he (peace and blessings be upon him) came out, Sayyiduna Bilal (may Allah be pleased with him) would call the iqamah upon seeing him (peace and blessings be upon him).

It is narrated from Sayyiduna Ali (may Allah be pleased with him): "The mu'adhdhin has more right over the adhan, and the imam has more right over the iqamah."
It has also been narrated from Sharik, from al-A'mash, from Abu Salih, from Abu Hurayrah as a saying of the Prophet (marfu'), but that is not mahfuz (preserved).
