Jabir (may Allah be pleased with him) narrated regarding the Hajj of Islam that the Prophet (peace be upon him) came to the place of standing at Arafat, delivered the first sermon to the people, then Bilal (may Allah be pleased with him) called the adhan, so the Prophet (peace be upon him) began the second sermon. When he (peace be upon him) finished his sermon, Bilal had finished the adhan. Then Bilal (may Allah be pleased with him) gave the iqamah and the Zuhr prayer was performed, then Bilal (may Allah be pleased with him) gave the iqamah and the Asr prayer was performed.
