Musnad Ahmad 33:922

Muhammad ibn Bakr narrated to us, Ibn Jurayj informed us, Abu al-Zubayr informed me that he heard Jabir ibn Abdullah saying, while he was reporting 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. The Prophet, may God bless him and grant him peace, said: "When you intend to set out for Mina, then enter into the state of Ihram." So we entered into the state of Ihram from al-Batha.
