Sahih+2

It was narrated from Ibn Abbas:That when the Messenger of Allah came to Dhul-Huaifah he marked the Hadi on the right side of its hump, then removed the blood from it, then he garlanded it with two shoes and mounted his she-camel. When it stood up with him in Al-Baida, he began the Talbiyah for Hajj and he entered Ihram at noon
