The Prophet ﷺ said, "There is no contagion, no Safar, and no hama."
أن النبي ﷺ قال: لا عدوى ولا صفر ولا هامة
Muslim narrated it in the Book of Greetings (2220: 103), from Abdullah bin Abdul-Rahman Darimi, from Abu Yaman, from Shuayb, from Zuhri, who said, Saaib bin Yazid, the nephew of Namir, narrated it to me, and he related it.
