Jabir bin Abdullah (may Allah be pleased with them both) narrated the hadith about the Hajj of the Prophet (peace and blessings be upon him) and described his (peace and blessings be upon him) stopping at Namirah: until, when the sun had passed the meridian, he ordered (his she-camel) al-Qaswa', and it was saddled for him. He (peace and blessings be upon him) mounted until he came to the middle of the valley and addressed the people. Then Bilal (may Allah be pleased with him) gave the adhan, then called the iqamah for Zuhr and he prayed; then he called the iqamah and he led the Asr prayer, and he did not pray anything between them.
