 Karamokho Alfa was known for his Islamic scholarship and piety . He respected the rights of the old " masters of the soil " , saying " it was Allah who had established them . " Despite this ruling , the <unk> reserved the right to <unk> land , since they held it in trust for the people . In effect the existing property owners were not displaced , but now had to pay <unk> as a form of rent . Karamoko Alfa ruled the <unk> state until 1748 , when his excessive <unk> caused him to become mentally unstable and Sori was selected as de facto leader .
