Ali عَلِيّ ٱبْن أَبِي طَالِب‎, is important to both Shias and Sunnis, politically and spiritually.^[17] The numerous biographical sources about Ali are often biased according to sectarian lines, but they agree that he was a pious Muslim, devoted to the cause of Islam and a just ruler in accordance with the Qur'an and the Sunnah.^[2] While Sunnis consider Ali the fourth and final of the Rashidun (rightly guided) caliphs, Shia Muslims regard Ali as the first Imam after Muhammad due to their interpretation of the events at Ghadir Khumm. Shia Muslims also believe that Ali and the other Shia Imams (all of whom are from the Ahl al-Bayt, Muhammad's household) are the rightful successors to Muhammad. Ali has also received recognition from a variety of non-Muslim organizations, such as the United Nations and the World Organization for Human Rights, for his governance and social justice

Zulfiqar also spelled Dhulfiqar (Arabic: ذو الفقار‎ Ḏū-l-Faqār or Ḏū-l-Fiqār) is said to be the sword of Ali ibn Abi Talib.
