Muhammad ibn Ali ibn Mahbub narrated from Mu'awiya ibn Hakim, from Abdullah ibn Al-Mughira, from Ibn Bukayr, from Zurara, from Abu Ja'far عليه السلام, who said: Imam عليه السلام said: "If he is affected by snow, let him look for the saddle pad of his mount and perform tayammum from its dust or something else he has with him. And if he is in a situation where he finds nothing but mud, then there is no harm in performing tayammum with it."
