The statement that disease is contagious, along with the hadith "There is no contagion"

Question:
He says: If someone says that so-and-so has a contagious disease, how is that when the Messenger (peace and blessings be upon him) said, "There is no contagion"?

Answer:
He should not be angry with him. This is a disease in which there is a condition that is feared, such that it is feared to spread, because contact may have an effect. However, there is no contagion, as the Prophet (peace and blessings be upon him) said. But contact may have an effect. For this reason, he (peace and blessings be upon him) said:
Another hadith: , meaning that contact may result in the transfer of the disease. And whoever has contact with [the sick] while trusting in Allah, so that people know that the matter is in the hand of Allah, then he owes nothing. For this reason, it came in another hadith that the Messenger took the hand of a star, saying, "Trust in Allah," but take precautions against the causes that customarily transfer the disease, whether or not to avoid contact, just as he (peace and blessings be upon him) said, "There is no disease unless it is confirmed." Take precautions or not, but it is not contagion; it may transfer, it may not transfer. For this reason, when a man said, "O Messenger of Allah, the camels are numerous like the gazelles, so is it permissible for a camel with scab to mix with them?" he (peace and blessings be upon him) said, "Who prevented the first [camel] from being prevented from the one who brought it down upon the first?"
The scabby one may enter [the herd] and not become scabby, but generally, if it mixes with the scabby one, it will be afflicted with scab. So, keep the scabby one away from the healthy ones, as a matter of taking precautions and avoiding danger. Yes.
