The hadith “…a person will want to get ona boat with his family and flee” in the Time of Hazrat Mahdi (as) refers to the refugees

Narrated from Abdullah bin Amr: He said: “In the time of Hazrat Mahdi (as), such a time will come upon people THAT A PERSON WILL WANT TO GET ON A BOAT WITH HIS FAMILY AND FLEE BUT THE TROUBLE THEY FACE WITHIN THE WAVES OF SEA BECOMES MORE SEVERE THAN THE ONE ON LAND.

(Nuaym bin Hammad, Kitab Al Fitan, Hadith. 1294)
