Sahih Bukhari
Afflictions and the End of the World
Volume: 009 / Book Number: 088 / Hadith Number: 202
Narrated Abu Huraira:
Allah's Apostle said, "There will be afflictions (in the near future) during which a sitting person will be better than a standing one, and the standing one will be better than the walking one, and the walking one will be better than the running one, and whoever will expose himself to these afflictions, they will destroy him. So whoever can find a place of protection or refuge from them, should take shelter in it."
