Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)

Bukhari :: Book 5 :: Volume 59 :: Hadith 703

Narrated Ibn Umar:

When the Prophet passed by Al-Hijr, he said, "Do not enter the dwelling places of those people who were unjust to themselves unless you enter in a weeping state lest the same calamity as of theirs should befall you." Then he covered his head and made his speed fast till he crossed the valley.
