Uqba ibn Amr

Uqba ibn Amr al-Ansari (عقبة بن عمرو الأنصاري), also known by his kunya Abu Mas'ud (أبو مسعود) al-Ansari was a companion of Muhammad. He was a prominent narrator of hadith, quoted in Sahih Bukhari, the most prominent source of Hadith among Sunni Muslims. He reportedly narrated 102 or more hadiths.

Life
Uqba belonged to Medina and was among those who were present in the Pledge of al-Aqaba and promised that they would protect Muhammad at the cost of their lives. He took part in all battles with Muhammad and is said to have fought heroically.

Uqba opposed the Kufan revolt against Uthman ((r. 644 – 656)), the third caliph of the Rashidun Caliphate. Uthman's successor Ali ((r. 656 – 661)) appointed Uqba as the governor of Kufa. Afterward, Uqba married his daughter Umm Bashir to Ali's son Hasan. The modern historian Wilferd Madelung suggests that Ali was hoping to strength his relations with Uqba. Hasan and Umm Bashir had two (or possibly three) children with Umm Bashir, with their eldest son Zayd, his daughter Umm al-Husayn. It is also held that the couple had another daughter named Umm al-Hasan.
