Yao Ming (born September 12, 1980) is a retired Chinese professional basketball player who last played for the Houston Rockets of the National Basketball Association (NBA). At the time of his final season, he was the tallest active player in the NBA, at 2.29 m (7 ft 6 in).

Yao, who was born in Shanghai, started playing for the Shanghai Sharks as a teenager, and played on their senior team for five years in the Chinese Basketball Association (CBA), winning a championship in his final year. After negotiating with the CBA and the Sharks to secure his release, Yao was selected by the Houston Rockets as the first overall pick in the 2002 NBA Draft. Yao was selected to start for the Western Conference in the NBA All-Star Game eight times, and was named to the All-NBA Team five times. He reached the NBA Playoffs four times, and the Rockets won a first-round series in the 2009 postseason, their first playoff series victory since 1997. However, Yao missed 250 regular-season games due to foot and ankle injuries in his final six seasons.

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.
