It was narrated from Ibn 'Abbas (رضي الله عنه) that

The Prophet (ﷺ) prayed Zuhr in Dhul-Hulaifah, then he called for his camel and he marked it on the right side of its hump, then he wiped the blood from it, then he garlanded it with two sandals. Then his mount was brought to him and when he reached al-Baida’, he entered ihram for Hajj.
