Ibn Abi Mulaika narrates that Sayyiduna Miswar bin Makhrama (may Allah be pleased with him) performed eighteen circuits (Tawaf) and offered two rak'ahs for each Tawaf, and said that the Messenger of Allah (peace and blessings be upon him) said: "O Banu Abd Manaf, if you remain the custodians of this House (the Noble Ka'bah) after me, then do not prevent anyone from performing Tawaf of this House; let him perform Tawaf at any hour of the day or night whenever he wishes."
