Narrated Um Qais bint Mihsan:
I heard the Prophet saying, "Treat with the Indian incense, for it has healing for seven diseases; it is to be sniffed by one having throat trouble, and to be put into one side of the mouth of one suffering from pleurisy." Once I went to Allah's Apostle with a son of mine who would not eat any food, and the boy passed urine on him whereupon he asked for some water and sprinkled it over the place of urine.
