“The Messenger of Allah (ﷺ) said: ‘There is no
‘Adwa, no omen, and no Hamah.’ A man stood up and said: ‘O
Messenger
of Allah, what if a camel has mange and another camel gets
mange from
it?’ He said: ‘That is the Divine decree. Who causes
the mange in the
first one?’”
Sunan Ibn Majah Book 31, Hadith 105
