59 — ʿAlī ibn al-Hasan narrated to me, from Yahyā ibn Abī Bukayr, who said: ʿAbbād ibn al-Walīd al-Qurashī narrated to us, saying: al-Hasan—may Allah be pleased with him—said, “The tongue is the commander of the body. If it leads the limbs into any wrongdoing, they do wrong; but if it exercises restraint, they too exercise restraint.”
