Sayyiduna Jabir (may Allah be pleased with him) said that at the time of the Conquest of Makkah, while he (peace and blessings be upon him) was in the valley of Batha', the Prophet (peace and blessings be upon him) ordered Sayyiduna Umar (may Allah be pleased with him): "Remove all the pictures in the House of Allah (the Ka'bah)." The Prophet (peace and blessings be upon him) did not enter the House of Allah until the pictures had been removed.
