It is narrated from Hazrat Ibn Umar (may Allah be pleased with them both) that a man stood before the Noble Prophet (peace and blessings be upon him) and asked, "O Messenger of Allah (peace and blessings be upon him)! What makes Hajj obligatory?" The Prophet (peace and blessings be upon him) replied, "Provision for the journey and a means of transport." The man asked, "O Messenger of Allah (peace and blessings be upon him)! What is Hajj?" The Prophet (peace and blessings be upon him) replied, "Becoming dusty and disheveled." The man asked, "O Messenger of Allah (peace and blessings be upon him)! Which Hajj is the best?" The Prophet (peace and blessings be upon him) replied, "The one in which Talbiyah is recited aloud and an animal is sacrificed."
