 In 940 , Ibn Ra 'iq , during his conflict over control of Syria with the Ikhshidids of Egypt , fought against them in an indecisive battle at Lajjun . During the battle , Abu Nasr al @-@ Husayn — the Ikhshidid general and brother of the Ikhshidid ruler , Muhammad ibn Tughj — was killed . Ibn Ra 'iq was remorseful at the sight of Husayn 's dead body and offered his seventeen @-@ year @-@ old son , Abu 'l @-@ Fath Muzahim , to Ibn Tughj " to do with him whatever they saw fit " . Ibn Tughj was honored by Ibn Ra 'iq 's gesture ; instead of executing Muzahim , he gave the latter several gifts and robes , then married him to his daughter Fatima .
