It is narrated from Hazrat Asma bint Umais. She says that the Messenger of Allah, peace and blessings be upon him, asked me, "With what do you take a laxative?" I replied, "With shubrum." The Prophet, peace and blessings be upon him, said, "That is a hot, strong purgative." Then I took a laxative with senna, so the Prophet, peace and blessings be upon him, said, "If there were anything that could cure death, it would be senna," or he said, "Senna is a cure even from death."
