Career
Towards the end of his reign, Askia Muhammad had become increasingly dependant on Ali Fulan, the Hugu-koray-koi (Master of the Palace interior). When the older son"s of Askia heard about this, they were angered as the post of Benga was very prestigious. Musa in particular was angry at his father and with Ali Fulan, he claimed that Askia did nothing but what Ali told him.
Askia had become blind, and none of the son"s were aware of it because Ali Fulan stuck so close to his side (at this time blindness would have disqualified a ruler as he would have been expected to lead his army into battle, as well as being bad omen).
