Muhammad ibn Ya‘qub, from Ali ibn Muhammad ibn Abdullah, from Ibn al-Barqi, from his father, from Abdullah ibn al-Fadl, from someone who narrated to him: Abu Abdillah عليه السلام, peace be upon him, said: "There are ten places in which prayer is not to be performed: mud, water, bathhouses, graves, the resting places along roads, ant colonies, camel resting spots, water channels, salty barren land (al-sabkha), and snow."
