مُوَطَّأُ مَالِكٍ
Muwatta Malik 65
Purity
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، أَنَّهُ سَمِعَ سَعِيدَ بْنَ الْمُسَيَّبِ، يُسْأَلُ عَنِ الْوُضُوءِ، مِنَ الْغَائِطِ بِالْمَاءِ فَقَالَ سَعِيدٌ إِنَّمَا ذَلِكَ وُضُوءُ النِّسَاءِ .
Yahya related to me from Malik from Yahya ibn Said that he heard someone ask Said ibn al-Musayyab about washing off excreta with water. Said said, "That is the way women wash."
