Sayyiduna Jubair bin Mut'im (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "O sons of Abd Manaf, do not ever prevent anyone from performing Tawaf of this Sacred House (the Ka'bah) or from offering prayer in it at any hour of the day or night, whenever he wishes." The wording of the hadith text is from the narration of Ali bin Khushram.
