Chapter 90: Tricks
Narrated 'Abdullah bin 'Amir bin Rabi 'a: 'Umar bin Al-Khattab left for Sham, and when he reached a placed called Sargh, he came to know
that there was an outbreak of an epidemic (of plague) in Sham. Then 'Abdur Rahman bin 'Auf told
him that Allah' s Messenger (ﷺ) said, "If you hear the news of an outbreak of an epidemic (plague) in a
certain place, do not enter that place: and if the epidemic falls in a place while you are present in it, do
not leave that place to escape from the epidemic." So 'Umar returned from Sargh.
