Rashidun armyThe Rashidun army (جيش الراشدين) was the core of the Rashidun Caliphate's armed forces during the early Muslim conquests in the 7th century. The army is reported to have maintained a high level of discipline, strategic prowess and organization, granting them successive victories in their various campaigns. In its time, the Rashidun army was a very powerful and effective force. The three most successful generals of the army were Khalid ibn al-Walid, who conquered Persian Mesopotamia and the Roman Levant, Abu Ubaidah ibn al-Jarrah, who also conquered parts of the Roman Levant, and Amr ibn al-As, who conquered Roman Egypt.
UthmanUthman ibn Affan (ʿUthmān bin ʿAffān; 573 or 576 – 17 June 656 CE), also spelled by Colloquial Arabic, Turkish, Persian and Urdu rendering Osman/Usman, was a second cousin, son-in-law and notable companion of the Islamic prophet Muhammad, as well as the third of the Rāshidun, or "Rightly Guided Caliphs". He played a major role in early Islamic history, and is known for having ordered the compilation of the standard version of the Quran. When Caliph Umar ibn al-Khattab died in office aged 60/61 years, Uthman, aged 68–71 years, succeeded him and was the oldest to rule as Caliph.
Succession to MuhammadThe succession to Muhammad is the central issue that split the Muslim community into several divisions in the first century of Islamic history, with the most prominent among these sects being the Shia and Sunni branches of Islam. Sunni Islam maintains that Abu Bakr was the legitimate successor to Muhammad on the basis of election. Shia Islam holds that Ali ibn Abi Talib was the designated successor to the Islamic prophet Muhammad.
Husayn ibn AliAbū ʿAbd Allāh al-Ḥusayn ibn ʿAlī ibn Abī Ṭālib (أبو عبد الله الحسين بن علي بن أبي طالب; 10 January 626 – 10 October 680) was a grandson of the Islamic prophet Muhammad and a son of Ali ibn Abi Talib and Muhammad's daughter Fatima, as well as a younger brother of Hasan ibn Ali. He is the third Imam of Shia Islam after his brother, Hasan, and before his son, Ali ibn Husayn Zayn al-Abidin. Being a grandson of the prophet, he is a member of the Ahl al-Bayt. He is also considered to be a member of the Ahl al-Kisa, and a participant in the event of Mubahala.
AliʿAlī ibn Abī Ṭālib (عَلِيّ بْن أَبِي طَالِب; 600 – 661 CE) was the last Caliph of the Rashidun Caliphate, the successor state to the Islamic prophet Muhammad's political dominions. He is considered by Shia Muslims to be the first Imam, the rightful religious and political successor to Muhammad. The issue of succession caused a major rift between Muslims and divided them into two major branches: Shia following an appointed hereditary leadership among Ali's descendants, and Sunni following political dynasties.
Abu BakrAbū Bakr ʿAbd Allāh ibn ʿAbī Quḥāfa (; 27 October 573 – 23 August 634) was the senior companion and was, through his daughter Aisha, a father-in-law of the Islamic prophet Muhammad, as well as the first Caliph of the Rashidun Caliphate. He is known with the honorific title al-Siddiq by Sunni Muslims. Abu Bakr was born in 573 CE to Abu Quhafa and Umm Khayr. He belonged to the tribe of Banu Taym. In the Age of Ignorance, he was a monotheist and condemned idol-worshipping. As a wealthy trader, Abu Bakr used to free slaves.
