In one narration the wording is: "Forgive the wives of the Ansar."
Ahmad recorded it, and al-Bazzar recorded something similar with the wording: "Welcome to the Ansar"; the Prophet (peace and blessings be upon him) said this three times. A similar narration is reported in al-Mu'jam al-Awsat, al-Mu'jam al-Saghir and al-Mu'jam al-Kabir, with the wording: "Forgive the daughters-in-law of the Ansar." One of the various chains of Ahmad has narrators who are the narrators of the Sahih.
