The Messenger of Allah ﷺ was asked about cleaning oneself after relieving himself, and he said, "With three stones, none of which contain dung."
حدثنا عبد الله بن محمد النفيلي حدثنا أبو معاوية عن هشام بن عروة عن عمرو بن خزيمة عن عمارة بن خزيمة
سئل رسول الله ﷺ عن الاستطابة فقال بثلاثة أحجار ليس فيها رجيع
[Its chain of transmission is daif] Ibn Majah narrated it in the Book of Purification, Chapter on Cleaning Oneself with Stones and the Prohibition of Using Dung and Bones, no. 315, from the hadith of Hisham bin Urwa, with this chain.Amr bin Khuzayma is of unknown status, no one but Ibn Hibban validated him as reliable, and the hadith in Muslim, no. 262, suffices in place of it.
