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.

Zulfikar Ali Bhutto (Urdu: ذوالفقار علی بھٹو, Sindhi: ذوالفقار علي ڀُٽو, IPA: [zʊlfɪqɑːɾ ɑli bʱʊʈːoː]) (5 January 1928 – 4 April 1979) was 9th Prime Minister of Pakistan from 1973 to 1977, and prior to that, 4th President of Pakistan from 1971 to 1973. Bhutto was the founder of the Pakistan Peoples Party (PPP) and served as its chairman until his execution in 1979. His elder daughter, Benazir Bhutto, later also served as Prime Minister, while his son Murtaza Bhutto served as member of Parliament of Pakistan.

Educated at the University of Southern California and University of California, Berkeley in the United States and the University of Oxford in the United Kingdom, Bhutto was noted for his progressive economic initiatives, industrialisation, education, and foreign policy, and his intellectualism. In addition to national security issues, Bhutto promoted his policies on nationalisation, health care, and social reforms. Under his premiership, Pakistan's Parliament gave approval and passed unanimously the 1973 Constitution of Pakistan, a supreme law that provides a parliamentary system to Pakistan, strengthened Sino-Pakistani and Saudi-Pakistani relations, recognised East-Pakistan as Bangladesh, and hosted the second Organisation of the Islamic Conference (OIC) in 1974 where he delegated and invited leaders from the Muslim world to Lahore, Punjab Province of Pakistan. In July 1972, Bhutto successfully proceeded the Shimla treaty, signed with Indira Gandhi of India, brought 93,000 Prisoners of War back to Pakistan, and secured 5,000 sq mi (13,000 km²) held by India. In 20 January 1972, weeks after the Indo-Pakistani 1971 winter war, Bhutto orchestrated, authorised, and administrated the scientific research on nuclear weapons; for this, he is colloquially known in the world as "Father of the Pakistan's nuclear deterrent programme".
