Ismail ibn al-Ash’ath said, “All ointments are sorrow, except the oil of oil, if he thinks that he eats it, then it is devolved with money, and the oil is devolved with sadness, and the oil of butter is devolved with money, the total beneficial and the spoil, as well as the fat of butter. On the one hand of a man of hardship, it was said that there is healing and comfort, and it was said that all the fats extracted from grains, hearts and plants shall be devolved with the money attributed to what was attributed to him and mentioned in his chapter .
