Hussein ibn ‘Alī ibn Abī Ṭālib (Arabic: حسين بن علي بن أبي طالب‎)‎ (3rd Sha'aban 4 AH – 10th Muharram 61 AH; 8 January 626 CE – 10 October 680 CE, also spelled Hussayn) was the son of ‘Alī ibn Abī Ṭālib (final Rashidun Caliph and first Shia Imam) and Fātimah Zahrā (daughter of the Islamic prophet Muhammad) and the younger brother of Hasan ibn Ali. Husayn is an important figure in Islam as he is a member of the Ahl al-Bayt (the household of Muhammad) and Ahl al-Kisa, as well as being a Shia Imam, and one of The Fourteen Infallibles of Shia Twelvers.

Husayn ibn ‘Alī is exalted by all the Shia as a martyr who fought tyranny as he refused to pledge allegiance to Yazid I, the Umayyad caliph. He rose up to create a regime that would reinstate a "true" Islamic polity as opposed to what he considered the unjust rule of the Umayyads. As a consequence, Husayn was killed and beheaded in the Battle of Karbala in 680 (61AH) by Shimr Ibn Thil-Jawshan. The annual funeral in the memory of him, his family, his children and his As'haab (companions) is called Ashura (tenth day of Muharram) and is a day of mourning for Shia Muslims.

Alī ibn Abī Ṭālib (Arabic: علي بن أﺑﻲ طالب, Transliteration: ʿAlī ibn Abī Ṭālib, [ʕaliː ibn ʔæbiː t̪ˤɑːlib]; 13^thRajab, 24 BH–21^stRamaḍān, 40 AH; approximately October 23, 598 or 600 or March 17, 599 – January 27, 661). The son of Abu Talib, Ali was also the cousin and son-in-law of Islamic prophet Muhammad, ruling over the Islamic Caliphate from 656 to 661, and was the first male convert to Islam.Sunnis consider Ali the fourth and final of the Rashidun (rightly guided Caliphs), while Shias regard Ali as the first Imam and consider him and his descendants the rightful successors to Muhammad, all of which are members of the Ahl al-Bayt, the household of Muhammad. This disagreement split the Ummah (Muslim community) into the Sunni and Shia branches.

Muslim sources, especially Shia ones, state that since Muhammad's time, Ali was the only person born in the Kaaba sanctuary in Mecca, the holiest place in Islam. His father was Abu Talib and his mother was Fatima bint Asad, but he was raised in the household of Muhammad, who himself was raised by Abu Talib, Muhammad's uncle, and Ali's father. When Muhammad reported receiving a divine revelation, Ali was the first male to accept his message, dedicating his life to the cause of Islam.

Prince Ali Bin Al-Hussein of Jordan (Arabic: الأمير علي بن الحسين‎) (born on 23 December 1975) is the fourth son of the late King Hussein of Jordan, and the second child of the king with his third wife, Queen Alia.

Before continuing his studies in the United States, he served in the Jordanian Special Forces as a pathfinder, earning his military freefall parachute wings.
