Ḥassān ibn Mālik ibn Baḥdal al-Kalbī, commonly known as Ibn Baḥdal (d. 688/89), was the Umayyad governor of Palestine and Jordan during the reigns of Mu'awiyah I (r. 661–680) and Yazid I (680–683), a senior figure in the caliph's court, and a chieftain of the Banu Kalb tribe.
 He owed his position both to his leadership of the powerful Kalb, a major source of troops, and his kinship with the Umayyads through his aunt Maysun bint Bahdal, who was the wife of Mu'awiyah and mother of Yazid.
 Following Yazid's death, Ibn Bahdal served as the guardian of his son and successor, Mu'awiyah II, until the latter's premature death in 684.
 Amid the political instability and rebellions that ensued in the caliphate, Ibn Bahdal threw his support behind Marwan I, who hailed from a different branch of the Umayyads.
 Ibn Bahdal and his tribal allies defeated Marwan's opponents at the Battle of Marj Rahit and secured for themselves the most prominent roles in the Umayyad administration and military.
A hadith ( or ; Arabic: حديث‎ ‎ "ḥadīth" , plural: ahadith, أحاديث , "ʼaḥādīth" ) is one of various reports describing the words, actions, or habits of the Islamic prophet Muhammad.
 The term comes from the Arabic language and means a "report", "account" or "narrative".
 Unlike the Qur'an, which is the same literary work recognized by all Muslims, the ahadith is not one single same collection.
Horr (Persian: حر‎ ‎ ) was a book by the Iranian author Ali Shariati about the historic Battle of Karbala in which Hussein, the grandson of the Muslim prophet Muhammad, was killed by Yazid.
 Horr was a commander of the army of Yazid during the battle.
 First involved in fighting Hussein, Horr defected from the army of Yazid, joined Hussein, and was killed by Yazid's forces.
 The book examines fate, choice, and predestination as portrayed by Horr's decision to switch sides during the fateful battle.
Atikah bint Yazid was an Umayyad princess.
 She was the daughter of Yazid I, and wife of Abd al-Malik ibn Marwan.
 Some called her "the scholar" cause she studied Muslim religion, especially Hadith.
 She was also called generous as she gave up all of her money to poor member of Abu Sufyan's Family.
Sayyidah Zaynab bint ‘Ali (Arabic: الـسَّـيّـدة زَيـنـب بـنـت عـلي‎ ‎ , Also: 'Zainab') was one of the daughters of the fourth Sunni caliph and the first Shia imam, ‘Ali and his first wife Fatimah.
 The Islamic "Nabi" (Arabic: نَـبِي‎ ‎ , Prophet) Muhammad was her maternal grandfather, and thus she is a member of his "Bayt" (Arabic: بَـيـت‎ ‎ , Household).
 Therefore, she is often revered not only for her admirable characteristics and actions, but also for her membership in, and continuation of, the biological line of Muhammad.
 Like other members of her family she became a great figure of sacrifice, strength, and piety in Islam – in the Sunni and Shi‘i sects of the religion.
 Zaynab married ‘Abdullah ibn Ja‘far, and had three sons and two daughters with him.
 When her brother, Imam Al-Husain, stood up against Yazid ibn Mu‘awiyah in 680 CE (61 AH), Zaynab accompanied him.
 She played an important role in protecting the life of her nephew, Imam ‘Ali ibn Al-Husayn, and because of her sacrifice and heroism, she became known as the "Heroine of Karbala’".
 Zaynab died in 681 CE, and her Masjid is located in Damascus, Syria, Ash-Sham.
Sunni Islam and Shia Islam are the two major denominations of Islam.
 Their division traces back to a schism following the death of the Islamic prophet Muhammad in the year 632AD.
 A dispute over succession to Muhammad as a caliph of the Islamic community spread across various parts of the world, which led to the Battle of Jamal and Battle of Siffin.
 The dispute intensified greatly after the Battle of Karbala, in which Hussein ibn Ali and his household were killed by the ruling Umayyad Caliph Yazid I, and the outcry for revenge divided the early Islamic community.
Sermon of Zaynab bint Ali in the court of Yazid are the critical statements by Zaynab bint Ali in Yazid presence in the aftermath of battle of Karbala when the captive family members of Muhammad, prophet of Islam, and the heads of those murdered were moved to the Levant (Arabic: شام‎ ‎ ) by the forces of Yazid I. Zaynab delivered a defiant sermon in the court of Yazid with the purpose of humiliating Yazid and exposing his army's atrocities while honoring the Ahl al-Bayt and those killed in Karbala and to relate the eternal consequences of the battle.
Bibi Pāk Dāman (Urdu: بی بی پاکدامن) is the mausoleum of Ruqayyah bint Ali located in Lahore, Punjab, Pakistan.
 Legend has it that it holds the graves of six ladies from Muhammad's household (Ahl Al-Bayt).
 Ruqayyah bint Ali ibn Abu Talib was the daughter of Muhammad's cousin and son-in-law Ali ibn Abu Talib with his wife Umm al banin bint Huzaam.
 Ruqayah bint Ali was the full sister of Al-Abbas ibn Ali and also the wife of Muslim ibn Aqeel (emissary of third Shi'a Imam Husayn ibn Ali to Kufah).
 Others are said to be Muslim ibn Aqil's sister and daughters.
 It is said that these ladies came here after the event of the battle of Karbala on the 10th day of the month of Muharram in 61 AH (October 10, AD 680).
 Bibi Pak Daman, which means the "chaste lady", is the collective name of the six ladies believed to interred at this mausoleum, though it is also (mistakenly) popularly used to refer to the personage of Ruqayyah bint Ali alone.
 They were among the women who brought Islam to South Asia, preaching and engaging in missionary activity in the environs of Lahore.
 It is said that Data Ganj Bakhsh, considered a great Sufi saint of the South Asia, was himself a devotee of the Bibi Pak Daman shrine and received holy knowledge from this auspicious shrine.
The Siege of Mecca in September–November 683 was one of the early battles of the Second Islamic Civil War.
 The city of Mecca served as a sanctuary for Abdallah ibn al-Zubayr, who was among the most prominent challengers to the dynastic succession to the Caliphate by the Umayyad Yazid I.
 After nearby Medina, the other holy city of Islam, also rebelled against Yazid, the Umayyad ruler sent an army to subdue Arabia.
 The Umayyad army defeated the Medinans and took the city, but Mecca held out in a month-long siege, during which the Kaaba was damaged by fire.
 The siege ended when news came of Yazid's sudden death.
 The Umayyad commander, Husayn ibn Numayr, after vainly trying to induce Abdallah to return with him to Syria and be recognized as Caliph, departed with his forces.
 Ibn al-Zubayr remained in Mecca throughout the civil war, but he was nevertheless soon acknowledged as Caliph across most of the Muslim world.
 It was not until 692, that the Umayyads were able to send another army which again besieged and captured Mecca, ending the civil war.
