Musannaf Ibn Abi Shaybah

Hazrat Ali (may Allah be pleased with him) used to break down enclosures (shelters), or he would order them to be broken.

Muhammad, may Allah have mercy on him, said: "It is my wish that all the enclosures (shelters) be demolished, and that the first of them to be demolished should be Abdullah's shelter."

Hazrat Harith narrates that Hazrat Shurayh (may Allah have mercy on him) would not allow any canopy to remain standing under which a horseman carrying his spear could not pass, and he used to say: "You have constructed a building over the horseman's spear."
