وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عَائِشَةَ، سُئِلَتْ عَنْ غُسْلِ الْمَرْأَةِ، مِنَ الْجَنَابَةِ فَقَالَتْ لِتَحْفِنْ عَلَى رَأْسِهَا ثَلاَثَ حَفَنَاتٍ مِنَ الْمَاءِ وَلْتَضْغَثْ رَأْسَهَا بِيَدَيْهَا ‏.‏

Yahya related to me from Malik that he had heard that A'isha wasasked about how a woman should do ghusl for major ritual impurity. Shesaid, "She should scoop water over her head with both hands threetimes and rub the roots of her hair with her hands." Translation Not Available
