Exegesis of the negation of contagion mentioned in the Prophetic hadiths

Question:
May Allah reward you with good and do you good. One of our sisters from Yanbu al-Bahr, Ummah of Allah, Ummah of Allah, has a collection of questions. In one of them she says: It was mentioned in a hadith from the Messenger What is the meaning of contagion here? Does this mean that we should not distance ourselves from contagious diseases? How do we compare this with the command of the Messenger (peace and blessings be upon him) not to enter a land where there is plague? And does his saying (peace and blessings be upon him) Does this hadith contradict what came before it? Please guide us, may Allah reward you with good.

Answer:
Contagion is the transmission of disease from one person to another due to contact and proximity to the infected person. Contagion is a reality and is known. The Prophet (peace and blessings be upon him), in his saying "There is no contagion, no bad omen, no hama, and no safar," intends the contagion that the people of the pre-Islamic age of ignorance (jahiliyyah) believed in. They believed that disease spreads by its nature without the permission of Allah (Glorified and Exalted is He). This is the belief of the people of the pre-Islamic age of ignorance.
As for believing that the origins of contagion and the transmission of disease are from Allah, that if He wills it spreads and affects the healthy, and if He wills (Glorified and Exalted is He) it does not spread, this is a correct belief.
Contact with the infected person is one of the causes of contagion, but the matter is in the hand of Allah (Mighty and Majestic). If He wills, this happens, and if He wills, it does not. A person relies upon Allah (Mighty and Majestic). As for his command (peace and blessings be upon him) to flee from the leper, and his command not to enter, his prohibition of entering a land where there is plague, this is avoiding the causes of danger. We are commanded to avoid the causes of danger, because entering a land with an epidemic is a cause of danger and infection, and likewise, contact with a leper is a cause of infection. We avoid the causes that may, by the permission of Allah, lead to bad consequences. Yes.
