Sunan Abi Dawud
حَدَّثَنَا أَحْمَدُ بْنُ صَالِحٍ، حَدَّثَنَا عَنْبَسَةُ، حَدَّثَنَا يُونُسُ، عَنِ ابْنِ شِهَابٍ، أَخْبَرَتْنِي عَمْرَةُ بِنْتُ عَبْدِ الرَّحْمَنِ، عَنْ أُمِّ حَبِيبَةَ، بِهَذَا الْحَدِيثِ قَالَتْ عَائِشَةُ رَضِيَ اللَّهُ عَنْهَا . فَكَانَتْ تَغْتَسِلُ لِكُلِّ صَلاَةٍ .
This tradition has been transmitted through a different chain of narrators. According to this version. 'Aishah said: She would wash herself for every prayer.
