It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) prayed at Dhu al-Hulayfah, then called for a sacrificial camel and marked the right side of its hump, then wiped the blood from it and garlanded it with two sandals. Then his mount was brought, and when he (peace and blessings be upon him) sat on it and it stood upright with him (peace and blessings be upon him) on al-Bayda', he (peace and blessings be upon him) raised his voice with the talbiyah.
