Abu Muhammad Lu'lu', surnamed al-Kabir ("the Elder") and al-Jarrahi al-Sayfi ("[servant] of the Jarrahids and Sayf al-Dawla"), is a military slave (ghulam) of the Hamdanid Emirate of Aleppo.

Under the rule of Sa'd al-Dawla, he rises to become the emirate's chamberlain, and on Sa'd al-Dawla's death in 991 he is appointed guardian of his son and successor, Sa'id al-Dawla.

The able Lu'lu' soon becomes the de facto ruler of the emirate, securing his position by marrying his daughter to the young emir.

His perseverance and aid from the Byzantine emperor Basil II preserves Aleppo from repeated Fatimid attempts to conquer it.

Upon Sa'id al-Dawla's death in 1002—possibly poisoned by Lu'lu'—he becomse the ruler of the emirate, disinheriting Sa'id al-Dawla's sons.

He rules with wisdom until his death in 1008/9.

He is succeeded by his son, Mansur, who manages to retain the throne until deposed in 1015/16.
