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

The Prophet of Allah (ﷺ) prayed in Dhul-Hulaifah, then he marked the hady on the right side of its hump, then he wiped the blood from it and garlanded it with two sandals. Then he rode his mount and when he reached al-Baida', he entered ihram. He said: He entered ihram at noon time. Abu Dawood said: For Hajj.
