مُرْنَ أَزْوَاجَكُنَّ أَنْ يَسْتَطِيبُوا بِالْمَاءِ فَإِنِّي أَسْتَحْيِيهِمْ مِنْهُ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَفْعَلُهُ .
It was narrated that 'Aishah said: "Tell your husbands to clean themselves with water, for I am too shy to tell them myself. The Messenger of Allah (ﷺ) used to do that."
