The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, commented: "Similarly, if any of the mentioned things - such as a mouse or dog - touches a person’s body or his hand, and it is wet, he should wash the affected area. But if it is dry, he should wipe it with soil." This ruling is supported by previous narrations and is further clarified by additional evidence.
