Kilab ibn Murrah (Arabic: كِلَاب بْن مُرَّة) (born c. 373 CE) was an ancestor of the Islamic prophet Muhammad.
Both his parents traced their lineage back to Fihr, the progenitor of the Quraysh, and further to Ismail (Ishmael), son of Ibrahim (Abraham).
[citation needed] He had two half-brothers, Taym ibn Murrah and Yaqazah ibn Murrah, through his father's second wife, Asma bint Adiy (Hind bint Harithah al-Bariqiyyah) of Asad.
[2] He was married to Fatimah bint Sa'd ibn Sayl, who bore him two sons.
After his death, his wife married Rabi'ah ibn Haram from the Banu Udhrah tribe.
