Maymunah reported: I brought water to the Messenger of Allah, peace and blessings be upon him, for his ritual bath from major impurity. He washed his hands two or three times, then he put his right hand in the vessel and poured it over his private parts, washing it with his left hand. Then, he struck the ground with his left hand and rubbed it hard, and performed ablution as for prayer. Then, he poured three handfuls of water over his head and washed the rest of his body. Then, he moved away from that place and washed his feet. I brought him a towel but he turned it away.

عَنْ مَيْمُونَة قَالَتْ أَدْنَيْتُ لِرَسُولِ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ غُسْلَهُ مِنَ الْجَنَابَةِ فَغَسَلَ كَفَّيْهِ مَرَّتَيْنِ أَوْ ثَلَاثًا ثُمَّ أَدْخَلَ يَدَهُ فِي الْإِنَاءِ ثُمَّ أَفْرَغَ بِهِ عَلَى فَرْجِهِ وَغَسَلَهُ بِشِمَالِهِ ثُمَّ ضَرَبَ بِشِمَالِهِ الْأَرْضَ فَدَلَكَهَا دَلْكًا شَدِيدًا ثُمَّ تَوَضَّأَ وُضُوءَهُ لِلصَّلَاةِ ثُمَّ أَفْرَغَ عَلَى رَأْسِهِ ثَلَاثَ حَفَنَاتٍ مِلْءَ كَفِّهِ ثُمَّ غَسَلَ سَائِرَ جَسَدِهِ ثُمَّ تَنَحَّى عَنْ مَقَامِهِ ذَلِكَ فَغَسَلَ رِجْلَيْهِ ثُمَّ أَتَيْتُهُ بِالْمِنْدِيلِ فَرَدَّهُ
