It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) was on one of his journeys when the time of prayer came. The people halted and looked for Sayyiduna Bilal (may Allah be pleased with him) but did not find him. Then a man stood and gave the adhan. Then Sayyiduna Bilal (may Allah be pleased with him) came, and the people said: Another man has given the adhan. The people waited; then Sayyiduna Bilal (may Allah be pleased with him) wanted to give the iqamah, so the Prophet (peace and blessings be upon him) said to him: "Wait, O Bilal; the iqamah should be given only by the one who gave the adhan."
Only Sa'id bin Rashid narrated it, and he is da'if (weak).
