Abu Bakr (Abdullah ibn Abi Quhafa) (Arabic: عبد الله بن أبي قحافة, Transliteration: ʿAbd Allāh ibn Abī Quḥāfah, c. 573 CE - 634 CE) also known as Abū Bakr as-Șiddīq (Arabic: أبو بكر الصديق) was a senior companion (Sahabi) and the father-in-law of the Islamic prophet Muhammad. He ruled over the Rashidun Caliphate from 632–634 CE when he became the first Muslim Caliph following Muhammad's death. As Caliph, Abu Bakr succeeded to the political and administrative functions previously exercised by Muhammad, since the religious function and authority of prophethood ended with Muhammad's death according to Islam. He was called Al-Siddiq (The Truthful) and was known by that title among later generations of Muslims.

As a young man, Abu Bakr became a cloth merchant and he traveled extensively in Arabia and neighboring lands in the Middle East, through which he gained both wealth and experience. He eventually came to be recognized as the chief of his clan. On his return from a business trip to Yemen, he was informed that in his absence Muhammad had openly declared his prophethood. Not long after, Abu Bakr accepted Islam and was the first person outside the family of Muhammad to openly become a Muslim. He was instrumental in the conversion of many people to the Islamic faith and early in 623, Abu Bakr's daughter Aisha was married to Muhammad, strengthening the ties between the two men.

Omar Suleiman (Arabic: عمر سليمان‎, Egyptian Arabic pronunciation: [ˈʕomɑɾˤ seleˈmæːn]; born 2 July 1936) is a former Egyptian army general, politician, diplomat, and intelligence officer. A leading figure in Egypt's intelligence system beginning in 1986, Suleiman was appointed to the long-vacant Vice Presidency by then-President Hosni Mubarak on 29 January 2011. On 11 February 2011, Suleiman announced Mubarak's resignation and ceased being Vice President; governing power was transferred to the Armed Forces Supreme Council, of which Suleiman is not a member. A new head of intelligence services was appointed by the ruling Supreme Council. Suleiman withdrew from the political scene and did not appear in public after announcing Mubarak's resignation.

Millions of Egyptian citizens involved in the Egyptian Revolution of 2011 opposed Suleiman or Mubarak remaining in power without elections taking place. Human rights groups tied Suleiman’s career to a regime marked by widespread human rights abuses, and asserted that many Egyptians "see Suleiman as Mubarak II." Torture victims and human rights groups charged that Suleiman oversaw the systematic use of torture on detainees and that in at least one instance he personally tortured a detainee during his career in intelligence. In response to the 2011 protests, Suleiman blamed foreign influence and appealed to protestors to go home.
