There is no transitive disease, no evil omen, no safar, no hama. A desert Arab said: Allah's, Messenger.... The rest of the hadith is the same.
Sahih Muslim Book 39, Hadith 141
← Previous Hadith There is no infection, no safar, no hama. A desert Arab said: Allah's Messenger, how is it that when the camel is in the sand it is like a deer-then a camel afflicted with scab mixes with it and it is affected by sub? He (the Holy Prophet) said: Who infected the first one?

Note: The majority of scholars interpret this to mean that these things in and of themselves do not transmit or cause harm through supernatural or hidden means but that Allah is ultimately in control and any fearful superstition around these is false.

Sahih Muslim Book 39, Hadith 140 Next Hadith → There is no trahsitive disease. Thereupon a desert Arab stood up. The rest of the hadith is the same and in the hadith transmitted on the authority of Zuhri' the Prophet (ﷺ) is reported to have said: There is no transitive disease, no safar, no hama.
