And Harmalah ibn Yahya narrated to me, saying: Ibn Wahb informed us, saying: Yunus informed me, from Ibn Shihab, that he was informed that Abdullah ibn Umar — may Allah be pleased with them both — said: I saw the Messenger of Allah, peace and blessings be upon him, mount his riding camel at Dhu al-Hulayfah, then he would enter into the state of ihram when the camel stood upright with him.
