Purification (Kitab Al-Taharah) - كتاب الطهارة
حدثنا محمد بن الوليد الدمشقي، حدثنا أبو مسهر، عن سعيد بن عبد العزيز، في " غسل واغتسل " . قال قال سعيد غسل رأسه وغسل جسده .
Explaining the meaning of the words ghassala and ightasala (that occur in tradition 345) Sa'id (b. 'Abd al-'Aziz) said: One should wash one's head and body well (And not that one should make one's wife wash).
