Narrated Ibn Abbas:
The Prophet married Maimuna while he was in the state of lhram but he consummated that marriage after finishing that state. Maimuna died at Saraf (i.e. a place near Mecca). Ibn 'Abbas added, The Prophet married Maimuna during the 'Umrat-al-Qada' (i.e. the 'Umra performed in lieu of the 'Umra which the Prophet could not perform because the pagans, prevented him to perform that 'Umra)
