《晋书·列传·第七章》
有关官吏奏请封他为江阳王，皇帝说： 司马睦退身平静地思考过失，重新修养自己的品德，如今有了爵位土地，不仅仅是因为赦免。
有司奏封江阳王，帝曰： 睦退静思愆，改修其德，今有爵土，不但以赦。
The official in charge memorialized to enfeoff him as King of Jiayang. The Emperor said, "Sima Mu has stepped back, calmly considered his faults, and cultivated his virtue afresh. Now he has title and lands; it is not just because of the amnesty."
