Battle of Hunayn in the context of "Muhammad after the conquest of Mecca"

Khalid ibn al-Walid ibn al-Mughira al-Makhzumi (died 642) was a 7th-century Arab military commander. He initially led campaigns against Muhammad on behalf of the Quraysh. He later became a Muslim and spent the remainder of his career serving Muhammad and the first two Rashidun caliphs, Abu Bakr and Umar, as a commander of the Muslim army. Khalid played leading command roles in the Ridda Wars against rebel tribes in Arabia in 632–633, the initial campaigns in Sasanian Iraq in 633–634, and the conquest of Byzantine Syria in 634–638.

As a horseman of the Quraysh's aristocratic Banu Makhzum clan, which ardently opposed Muhammad, Khalid played an instrumental role in defeating Muhammad and his followers during the Battle of Uhud in 625. In 627 or 629, he converted to Islam in the presence of Muhammad, who inducted him as an official military commander among the Muslims and gave him the title of Sayf Allah (lit. 'Sword of God'). During the Battle of Mu'ta, Khalid coordinated the safe withdrawal of Muslim troops against the Byzantines. He also led the Bedouins under the Muslim army during the Muslim conquest of Mecca in 629–630 and the Battle of Hunayn in 630. After Muhammad's death, Khalid was appointed to Najd and al-Yamama to suppress or subjugate the Arab tribes opposed to the nascent Muslim state; this campaign culminated in Khalid's victory over rebel leaders Tulayha and Musaylima at the Battle of Buzakha in 632 and the Battle of Yamama in 633, respectively.

Sakhr ibn Harb ibn Umayya (Arabic: صَخْرِ ٱبْن حَرْب ٱبْن أُمَيَّةَ, romanized: Ṣakhr ibn Ḥarb ibn Umayya; c. 560—653), commonly known by his kunya Abu Sufyan (Arabic: أَبُو سُفْيَانُ, romanized: Abū Sufyān), was a prominent opponent-turned companion and father-in-law of the Islamic prophet Muhammad. He was the father of the first Umayyad caliph Mu'awiya I (r. 661–680) and namesake of the Sufyanid line of Umayyad caliphs which ruled from 661 to 684.

Abu Sufyan was a leader and merchant from the Quraysh tribe of Mecca. During his early career, he often led trade caravans to Syria. He had been among the main leaders of Meccan opposition to Muhammad, the prophet of Islam, commanding the Meccans at the battles of the Uhud and Trench in 625 and 627 CE. However, when Muhammad entered Mecca in 630, he was among the first to submit and was given a stake in the nascent Muslim state, playing a role at the Battle of Hunayn and the subsequent destruction of the polytheistic sanctuary of al-Lat in Ta'if. After Muhammad's death, he may have been appointed as the governor of Najran by Caliph Abu Bakr (r. 632–634) for an unspecified period. Abu Sufyan later played a supporting role in the Muslim army at the Battle of the Yarmuk against the Byzantines in Syria. His sons Yazid and later Mu'awiya were given command roles in that province and the latter went on to establish the Umayyad Caliphate in 661.

Abu al-A'war Amr ibn Sufyan ibn Abd Shams al-Sulami (Arabic: أبو الأعور عمرو بن سُفيان بن عبد شمس السلمي, romanized: ʾAbū al-ʾAʿwar ʿAmr ibn Sufyān ibn ʿAbd Shams al-Sulamī), identified with the Abulathar or Aboubacharos (Greek: Ἀβουλαθάρ, Ἀβουβάχαρος) of the Byzantine sources (fl. 629–669), was an Arab admiral and general, serving in the armies of the Rashidun caliphs Abu Bakr (r. 632–634), Umar (r. 634–644) and Uthman (r. 644–656) rejecting the fourth Rashidun caliph Ali (r. 656–661), instead serving Umayyad caliph Mu'awiya I (r. 661–680).

He was one of the last prominent members of the Banu Sulaym tribe to convert to Islam, and fought against Muhammad at the Battle of Hunayn in 630. After becoming a Muslim, he took part in the conquest of Syria in the 630s and fought at the Yarmuk. Later, he commanded the Arab navy during the campaigns against the Byzantines in the eastern Mediterranean, including the decisive Muslim victory at the Battle of the Masts in 654. His army was also allegedly responsible for the destruction of the colossus of Rhodes. From the First Fitna until his disappearance from the historical record in the 660s, Abu al-A'war served Mu'awiya in a number of capacities, including as a commander and negotiator at the Battle of Siffin, an operative of Amr ibn al-As in Egypt, a tax administrator in Palestine and the governor of Jordan; he had held the latter post since the reign of Uthman.

The Hawazin (Arabic: هوازن / ALA-LC: Hawāzin) were an Arab tribe originally based in the western Najd and around Ta'if in the Hejaz. They formed part of the larger Qays tribal group. The Hawazin consisted of the subtribes of Banu Sa'd, and Banu Jusham, as well as the powerful Banu Thaqif and Banu Amir, which were both often counted separately from the Hawazin.

The tribe often clashed with their one-time patrons, the Ghatafan, and on occasion, sub-tribes of the Hawazin fought each other. The tribe had little contact with the Islamic prophet Muhammad until 630 when they were defeated by Muhammad's forces at the Battle of Hunayn. The Hawazin tribe were one of the first to rebel and fight against the early Muslim state based in Medina during the Ridda wars, which followed Muhammad's death in 632.
