It is narrated from Hazrat Abu Tha’labah (may Allah be pleased with him) that when the Prophet (peace and blessings be upon him) camped at any place with an army, the people would scatter in different ravines and valleys. (Once this happened, so) the Prophet (peace and blessings be upon him) stood up and said: Your scattering in these ravines and valleys is because of Satan. The narrator says that after this, whenever they camped at any place, the people would stay so close to each other that you could say if a single sheet were spread over them, it would cover them all.
