`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 `AbdurRahman 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.
Sahih al-Bukhari Book 90, Hadith 20
← Previous Hadith Allah's Messenger (ﷺ) used to like sweets and also used to like honey, and whenever he finished the `Asr prayer, he used to visit his wives and stay with them. Once he visited Hafsa and remained with her longer than the period he used to stay, so I enquired about it. It was said to me, "A woman from her tribe gave her a leather skin containing honey as a present, and she gave some of it to Allah's Messenger (ﷺ) to drink." I said, "By Allah, we will play a trick on him." So I mentioned the story to Sauda (the wife of the Prophet) and said to her, "When he enters upon you, he will come near to you whereupon you should say to him, 'O Allah's Messenger (ﷺ)! Have you eaten Maghafir?' He will say, 'No.' Then you say to him, 'What is this bad smell? ' And it would be very hard on Allah's Messenger (ﷺ) that a bad smell should be found on his body. He will say, 'Hafsa has given me a drink of honey.' Then you should say to him, 'Its bees must have sucked from the Al-`Urfut (a foul smelling flower).' I too, will tell him the same. And you, O Saifya, say the same." So when the Prophet (ﷺ) entered upon Sauda (the following happened). Sauda said, "By Him except Whom none has the right to be worshipped, I was about to say to him what you had told me to say while he was still at the gate because of fear from you. But when Allah 's Apostle came near to me, I said to him, 'O Allah's Messenger (ﷺ)! Have you eaten Maghafir?' He replied, 'No.' I said, 'What about this smell?' He said, 'Hafsa has given me a drink of honey.' I said, 'Its bees must have sucked Al-`Urfut.' " When he entered upon me, I told him the same as that, and when he entered upon Safiya, she too told him the same. So when he visited Hafsa again, she said to him, "O Allah's Messenger (ﷺ)! Shall I give you a drink of it (honey)?" He said, "I have no desire for it." Sauda said, Subhan Allah! We have deprived him of it (honey)." I said to her, "Be quiet!"

Sahih al-Bukhari Book 90, Hadith 19 Next Hadith → That he heard Usama bin Zaid speaking to Sa`d, saying, "Allah's Messenger (ﷺ) mentioned the plague and said, 'It is a means of punishment with which some nations were punished and some of it has remained, and it appears now and then. So whoever hears that there is an outbreak of plague in some land, he should not go to that land, and if the plague breaks out in the land where one is already present, one should not run away from that land, escaping from the plague."
