Sunan Abi Dawud, Hadith 3139 ⓘ
Narrated Umm 'Atiyyah : The Messenger of Allah said to them while washing her daughter: Begin with her right side, and the places where the ablution is performed.
حَدَّثَنَا أَبُو كَامِلٍ، وَحَدَّثَنَا إِسْمَاعِيلُ، حَدَّثَنَا خَالِدٌ، عَنْ حَفْصَةَ بِنْتِ سِيرِينَ، عَنْ أُمِّ عَطِيَّةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ لَهُنَّ فِي غُسْلِ ابْنَتِهِ " ابْدَأْنَ بِمَيَامِنِهَا وَمَوَاضِعِ الْوُضُوءِ مِنْهَا " .
