Sahih Muslim Book 26, Hadith Number 5511.

Chapter : There is no infection, no evil omen, no Hama, no safar, no star promising rain, no ghoul and the ill should not go to those who are healthy.

Abu Huraira reported Allah’s Messenger (may peace be upon him) as saying: There is no transitive disease and he also reported along with it: The ill should not be taken to the healthy.
