Sayyida Umm Qais bint Mihsan (may Allah be pleased with her) narrates: I brought my son to the service of the Prophet Muhammad (peace and blessings be upon him). I had rubbed his throat because of swelling in his throat. The Prophet (peace and blessings be upon him) said: "Why do you cause pain to your children by rubbing their throats like this? It is obligatory upon you to use Indian aloeswood (oud al-hindi), for it contains seven types of cures. In the case of swelling in the throat, it should be administered through the nose, and in the case of pleurisy, it should be dripped under the tongue." Zuhri says: The narrator named Ubaydullah mentioned two things but did not mention the remaining five (i.e., for which other five diseases is it a cure?).
Imam Humaydi (may Allah have mercy on him) says: By 'oud al-hindi' is meant 'qist'.
