[7] The Arab traditions relate that Qedar was the son of Ishmael and his wife, the daughter of the chief of the Jurhum tribe.

[8] Qedar and his brother Nebaioth also become the caretakers of the Kaaba in Mecca after the death of their father, before their maternal grandfather takes over the role later on.

[8][9][10] Ibn Hisham, however, proposes a different lineage and believes that Muhammad is descended from Nebaioth (the firstborn son of Ishmael) and not Qedar.

[13] The city of Qeydar, named after Qedar, contains a tomb dedicated to him which was built in the 14th century during the Mongol Ilkhanate rule.

The room where the tomb is situated in is topped by a brick dome and the grave itself is covered by a wooden zarih.
