Khalid ibn al-Walid
Khalid was married to Asma, a daughter of Anas ibn Mudrik, a prominent chieftain and poet of the Khath'am tribe. Their son Abd al-Rahman became a reputable commander in the Arab–Byzantine wars and a close aide of Mu'awiya ibn Abi Sufyan, the governor of Syria and later founder and first caliph of the Umayyad Caliphate, serving as the latter's deputy governor of the Homs–Qinnasrin–Jazira district. Another son of Khalid, Muhajir, was a supporter of Ali, who reigned as caliph in 656–661, and died fighting Mu'awiya's army at the Battle of Siffin in 657 during the First Muslim Civil War. Following Abd al-Rahman's death in 666, allegedly as a result of poisoning ordered by Mu'awiya, Muhajir's son Khalid attempted to take revenge for his uncle's slaying and was arrested, but Mu'awiya later released him after Khalid paid the blood money. Abd al-Rahman's son Khalid was a commander of a naval campaign against the Byzantines in 668 or 669.
There is no further significant role played by members of Khalid's family in the historical record. His male line of descent ended toward the collapse of the Umayyad Caliphate in 750 or shortly after when all forty of his male descendants died in a plague in Syria, according to the 11th-century historian Ibn Hazm. As a result, his family's properties, including his residence and several other houses in Medina, were inherited by Ayyub ibn Salama, a great-grandson of Khalid's brother al-Walid ibn al-Walid. They remained in the possession of Ayyub's descendants until at least the late 9th century.
The family of the 12th-century Arab poet Ibn al-Qaysarani claimed descent from Muhajir ibn Khalid, though the 13th-century historian Ibn Khallikan notes the claim contradicted the consensus of Arabic historians and genealogists that Khalid's line of descent terminated in the early Islamic period. A female line of descent may have survived and was claimed by the 15th-century Sufi religious leader Siraj al-Din Muhammad ibn Ali al-Makhzumi of Homs. Kizil Ahmed Bey, the leader of the Isfendiyarids, who ruled a principality in Anatolia until its annexation by the Ottomans, fabricated his dynasty's descent from Khalid. The Sur tribe under Sher Shah, a 16th-century ruler of India, also claimed descent from Khalid.

Mausoleum in Homs: Starting in the Ayyubid period in Syria (1182–1260), Homs has obtained fame as the location of the purported tomb and mosque of Khalid. The 12th-century traveler Ibn Jubayr noted that the tomb contained the graves of Khalid and his son Abd al-Rahman. Muslim tradition since then has placed Khalid's tomb in the city. The building was altered by the first Ayyubid sultan Saladin (r. 1171–1193) and again in the 13th century. The Mamluk sultan Baybars (r. 1260–1277) attempted to link his own military achievements with those of Khalid by having an inscription honoring himself carved on Khalid's mausoleum in Homs in 1266. During his 17th-century visit to the mausoleum, the Muslim scholar Abd al-Ghani al-Nabulsi agreed that Khalid was buried there but also noted an alternative Islamic tradition that the grave belonged to Mu'awiya's grandson Khalid ibn Yazid. The current mosque dates to 1908 when the Ottoman authorities rebuilt the structure.
