What did the Prophet Muhammad (saw) say upon passing by Al-Hijr?
 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.
