Narrated ‘Abdullah bin ‘Umar:
Allah’s Apostle said, “Do not enter (the places) of these people where Allah’s punishment had fallenĀ unless you do so weeping. If you do not weep, do not enter (the places of these people) because Allah’sĀ curse and punishment which fell upon them may fall upon you.”
Sahih Bukhari, Volume 1, Book8, Number 425
