Read the quotation from al omari, an egyptian historian.

this man [mansa musa] spread upon cairo the flood of his generosity: there was no person, officer of the court, or holder of any office of the sultanate who did not receive a sum of gold from him. the people of cairo earned incalculable sums from him, whether by buying and selling or by gifts. so much gold was current in cairo that it ruined the value of the money . .
