Musnad Ahmad 27:888

I read to Abd al-Rahman, [from] Malik, and Rawh narrated to us, [saying] Malik narrated to us, from Musa ibn Uqbah, from Salim, from his father, that he said: "This Bayda' of yours, which you attribute falsely to the Messenger of Allah (peace and blessings of Allah be upon him) regarding it—the Messenger of Allah (peace and blessings of Allah be upon him) did not enter into Ihram except from by the mosque," meaning the mosque of Dhu al-Hulayfah. Abd al-Rahman said: And I have heard it from Malik.
