Musnad Ahmad 33:303

Yahya narrated to us, from Ibn Jurayj, Abu al-Zubayr informed me, he said: I heard Jabir ibn Abdullah saying, while he was informing about the Hajj of the Prophet, may God bless him and grant him peace, he said: "He commanded us, after we had performed the circumambulation (Tawaf), to exit the state of Ihram. He said: 'So when you intend to set out to Mina, then enter into the state of Ihram (for Hajj).'" So we entered into the state of Ihram from al-Batha.
