Hazrat Ali (radhiyallahu ‘anhu) reports that on one occasion, Rasulullah (sallallahu ‘alaihi wasallam) attended a janaazah of a certain Sahaabi. He then addressed the Sahaabah (radhiyallahu ‘anhum) who were present and said, “Who among you will go back to Madinah Munawwarah, and wherever he sees any idol or statue, he will break it, and wherever he sees any grave which is raised (high above the ground, or has a structure built on it), he will level it (to the normal height), and wherever he sees any picture (of animate objects), then he will immediately erase it?”
