Humran said :
I saw ‘Uthman b. ‘Affan performing ablution. He then narrated the same tradition. In this version there is no mention of rinsing the mouth and snuffing up water. This traditions adds : “He wiped his head three times. He then washed his feet three times. He then said : I saw the Messenger of Allah ﷺ performing ablution in like manner. He (the Prophet) said: He who performs ablution less than this, it is sufficient for him. 73 The narrator did not mention prayer (in this version).

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا الضَّحَّاكُ بْنُ مَخْلَدٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ وَرْدَانَ، حَدَّثَنِي أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ، حَدَّثَنِي حُمْرَانُ، قَالَ رَأَيْتُ عُثْمَانَ بْنَ عَفَّانَ تَوَضَّأَ . فَذَكَرَ نَحْوَهُ وَلَمْ يَذْكُرِ الْمَضْمَضَةَ وَالاِسْتِنْشَاقَ وَقَالَ فِيهِ وَمَسَحَ رَأْسَهُ ثَلاَثًا ثُمَّ غَسَلَ رِجْلَيْهِ ثَلاَثًا ثُمَّ قَالَ رَأَيْتُ رَسُولَ اللَّهِ ﷺ تَوَضَّأَ هَكَذَا وَقَالَ " مَنْ تَوَضَّأَ دُونَ هَذَا كَفَاهُ " . وَلَمْ يَذْكُرْ أَمْرَ الصَّلاَةِ .
