The Prophet married Maimuna during the `Umrat-al-Qada' (i.e. the `Umra performed in lieu of the `Umra which the Prophet (ﷺ) could not perform because the pagans, prevented him to perform that `Umra).
Sahih al-Bukhari Book 64, Hadith 293
← Previous Hadith The Prophet (ﷺ) 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).
