Hadith 6:146
Al-Thaqafi narrated to us, from Ayyub, from Muhammad, that he used to dislike that any hair be taken from the pubic area or any nail be clipped after death. And he used to say: "It is appropriate for the family of the sick person to do that while he is in his critical illness."
حدثنا الثقفي عن أيوب عن محمد انه كان يكره أن يؤخذ من عانة أو ظفر بعد الموت وكان يقول ينبغي لأهل المريض أن يفعلوا ذلك في ثقله
