The Prophet (ﷺ) said, "If you hear of an outbreak of plague in a land, do not enter it; but if the plague breaks out in a place while you are in it, do not leave that place."
The Prophet (ﷺ) said, "If somebody takes some `Ajwa dates every morning, he will not be affected by poison or magic on that day till night." (Another narrator said seven dates).
I heard Allah's Messenger (ﷺ) saying, "If Somebody takes seven 'Ajwa dates in the morning, neither magic nor poison will hurt him that day."
