Ibn Battuta compared Sulayman unfavorably to his brother, regarding him as a miser in comparison to Musa's renowned generosity.
[6][7] After Abu al-Hasan's death in 1351, Sulayman's court held a memorial feast for him in 1352, which was attended by the Moroccan explorer Ibn Battuta, who had recently arrived in Mali.
While Ibn Battuta was in Mali, Sulayman imprisoned his principal wife Qasa and replaced her with one of his other wives, Banju.
Facing criticism from his court, Sulayman accused Qasa of conspiring to overthrow him with an exiled member of the royal family named Jatil, who may have been Magha's son.
[16][12] The dates of the beginning and end of Sulayman's reign are not precisely known, and the evidence provided by the available primary sources is contradictory.
According to Ibn Khaldun, a caravan bearing gifts sent by Mansa Jata soon after he took power arrived in Fez in December 1360 or January 1361.
[g] The time between the conquest of Tlemcen and arrival of Jata's delegation is too short to accommodate the reign lengths Ibn Khaldun attributes to Magha, Sulayman, and Qasa.
It is possible that it was Maghan, rather than Musa, who sent the delegation in 1337, but this nonetheless leaves Sulayman's reign at least a year shorter than reported by Ibn Khaldun.
[27] Ibn Battuta remarked positively on the security of the Mali Empire during Sulayman's reign, noting that there was no need to worry about thieves.
[28] However, Sulayman's legacy has suffered from unfavorable comparisons to his more renowned brother,[5] and Ibn Battuta described him as "a miserly king from whom no great donation is to be expected.
[23] Niane identified Sulayman with Mansa Sama, a descendant of Sunjata said in oral tradition to have built the Kamabolon, a shrine in Kangaba.
