Narrated Um-'Atiya:

that the Prophet at the time of washing his deceased daughter had said to them, "Start from the right side beginning with those parts which are washed in ablution."

حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا إِسْمَاعِيلُ، قَالَ حَدَّثَنَا خَالِدٌ، عَنْ حَفْصَةَ بِنْتِ سِيرِينَ، عَنْ أُمِّ عَطِيَّةَ، قَالَتْ قَالَ النَّبِيُّ ﷺ لَهُنَّ فِي غُسْلِ ابْنَتِهِ " ابْدَأْنَ بِمَيَامِنِهَا وَمَوَاضِعِ الْوُضُوءِ مِنْهَا ".
