Sahih Muslim Book - 3, Hadith - 729

حَدَّثَنَا هَارُونُ بْنُ سَعِيدٍ الْأَيْلِيُّ حَدَّثَنَا ابْنُ وَهْبٍ أَخْبَرَنِي مَخْرَمَةُ بْنُ بُكَيْرٍ عَنْ أَبِيهِ عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ قَالَ قَالَتْ عَائِشَةُ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا اغْتَسَلَ بَدَأَ بِيَمِينِهِ فَصَبَّ عَلَيْهَا مِنْ الْمَاءِ فَغَسَلَهَا ثُمَّ صَبَّ الْمَاءَ عَلَى الْأَذَى الَّذِي بِهِ بِيَمِينِهِ وَغَسَلَ عَنْهُ بِشِمَالِهِ حَتَّى إِذَا فَرَغَ مِنْ ذَلِكَ صَبَّ عَلَى رَأْسِهِ قَالَتْ عَائِشَةُ كُنْتُ أَغْتَسِلُ أَنَا وَرَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِنْ إِنَاءٍ وَاحِدٍ وَنَحْنُ جُنُبَانِ.

It was narrated that Abu Salamah bin 'Abdur-Rahman said: "'Aishah said: 'When the Messenger of Allah (s.a.w) performed Ghusl, he would start with his right hand, pouring water onto it and washing it. Then he would pour water onto the harm (impurity) that was on him with his right hand, and wash it off with his left hand. When he had finished that, he would pour water over his head.' 'Aishah said: The Messenger of Allah (s.a.w) and I used to perform Ghusl from a single vessel, when we were Junub."
