Majma al-Zawaid — Hadith 3823

Umm Tariq, the freed slave-woman of Sayyiduna Sa'd (may Allah be pleased with him), narrates: The Prophet (peace and blessings be upon him) came to the house of Sayyiduna Sa'd (may Allah be pleased with him) and asked permission to enter, but Sayyiduna Sa'd (may Allah be pleased with him) remained silent. He asked permission again, and Sayyiduna Sa'd (may Allah be pleased with him) again remained silent. The Prophet (peace and blessings be upon him) asked permission once more, and Sayyiduna Sa'd (may Allah be pleased with him) again remained silent, so the Prophet (peace and blessings be upon him) turned back. Umm Tariq says: Sayyiduna Sa'd (may Allah be pleased with him) sent me to the Prophet (peace and blessings be upon him) to say that we did not give you permission only because we wanted you to keep giving us more (that is, to keep saying "Assalamu alaykum" more). Umm Tariq says: I heard a voice at the door asking permission to enter, but I could not see anything. The Prophet (peace and blessings be upon him) asked: "Who are you?" It said: "Umm Mildam (that is, fever)." The Prophet (peace and blessings be upon him) said: "You are neither welcome nor greeted. Will you go to the people of Quba'?" It said: "Yes." The Prophet (peace and blessings be upon him) said: "Then go to them."
Ahmad and al-Tabarani recorded it in al-Mu'jam al-Kabir, and its narrators are thiqat (trustworthy).
