If you get news of the outbreak of a plague in a land, do not enter it, and if it breaks out in a land in which you are, do not leave it

Explanation of the hadith

If a plague or epidemic breaks out in a part of the world that the person is not in, then it is not permissible for him to enter that plagued land so as to protect his health and the health of others. If the plague breaks out in a land that he is already in, then it is not permissible for him to leave that land, and he should be patient and accept whatever Allah decrees for him to receive the due reward for that.
