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).
حَدَّثَنَا مُحَمَّدُ بْنُ الْوَلِيدِ الدِّمَشْقِيُّ، حَدَّثَنَا أَبُو مُسْهِرٍ، عَنْ سَعِيدِ بْنِ عَبْدِ الْعَزِيزِ، فِي " غَسَّلَ وَاغْتَسَلَ " . قَالَ قَالَ سَعِيدٌ غَسَّلَ رَأْسَهُ وَغَسَلَ جَسَدَهُ .
