Abdullah bin Muhammad narrates from his father, from his grandfather (Sayyiduna Abdullah bin Zaid, may Allah be pleased with him): When he saw the method of the adhan in a dream, the Noble Prophet (peace and blessings be upon him) ordered Sayyiduna Bilal (may Allah be pleased with him), so he gave the adhan. Then the Noble Prophet (peace and blessings be upon him) ordered Sayyiduna Abdullah bin Zaid (may Allah be pleased with him), so he gave the iqamah.
