What are the impurities that, if found on clothing or in a place, would deem them impure, and does touching these impurities make the hand impure?

Scholars have agreed upon the impurity (najāsa) of only four things: the carcass of an animal with non-aquatic blood, pork, profusely flowing blood, and human urine and feces. As for the Malikis, impurities include: semen (which is recommended to be washed), pre-seminal fluid (madhī), prostatic fluid (wadī), pus, serous fluid, vaginal discharge from an animal whose meat is impermissible to eat and whose urine is impure, profusely flowing blood, black blood (sūda’), human urine and feces, urine and feces of animals whose meat is impermissible or disliked to eat, anything that intoxicates the mind, such as intoxicants, rotten eggs, substances expelled after death from an impure animal, urine and feces of an animal whose meat is permissible to eat if it has consumed impure substances for a period, altered vomit, the carcass of a terrestrial animal with flowing blood that was not slaughtered Islamically, parts separated from an impure animal upon its death, the quill of a feather, and the skin of a carcass. Dry impurity does not render what it touches impure if nothing from it adheres to the touched object.
