  Much of what is known about Musa comes from Arabic sources written after his hajj, especially the writings of Al-Umari and Ibn Khaldun. While in Cairo during his hajj, Musa befriended officials such as Ibn Amir Hajib, who learned about him and his country from him and later passed on that information to historians such as Al-Umari. Additional information comes from two 17th-century manuscripts written in Timbuktu, the Tarikh Ibn al-Mukhtar and the Tarikh al-Sudan. Oral tradition, as performed by the jeliw (sg. jeli), also known as griots, includes relatively little information about Musa compared to some other parts of the history of Mali.
