Sayyiduna Jabir (may Allah be pleased with him) said concerning the Hajj of Islam that the Prophet (peace and blessings be upon him) went to the standing place and gave the people the first sermon at Arafah. Then Sayyiduna Bilal (may Allah be pleased with him) gave the adhan. Then the Prophet (peace and blessings be upon him) began the second sermon. When he (peace and blessings be upon him) had finished the sermon and Sayyiduna Bilal (may Allah be pleased with him) the adhan, Sayyiduna Bilal (may Allah be pleased with him) called the iqamah, and he (peace and blessings be upon him) led Zuhr. Then he called the iqamah and he led the Asr prayer.
The Shaykh said: Ibrahim bin Muhammad bin Abi Yahya is alone in narrating this detail. The hadith of Hatim bin Isma'il contains what indicates that he gave the sermon and then Sayyiduna Bilal (may Allah be pleased with him) gave the adhan, but it does not mention the Prophet (peace and blessings be upon him) beginning the second sermon. And Allah knows best.
