Musnad Ahmad 25:1250

Muhammad ibn Bakr narrated to us, Sa’id and ‘Abd al-Wahhab informed us, from Sa’id, from Qatadah, and Ya’la ibn Hakim, from ‘Ikrimah, from Ibn ‘Abbas: "The Messenger of Allah (peace and blessings of Allah be upon him) married Maymunah bint al-Harith while he was in the state of ihram." He said: And in the hadith of Ya’la ibn Hakim: "He consummated the marriage with her at a water [place] called Sarif. When he completed his rites, he held the wedding feast with her at that water."
