Muwatta Malik #95
Purity
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ، أَنَّهُ قَالَ كُنْتُ مَعَ عَبْدِ اللَّهِ بْنِ عُمَرَ فِي سَفَرٍ فَرَأَيْتُهُ بَعْدَ أَنْ طَلَعَتِ الشَّمْسُ تَوَضَّأَ ثُمَّ صَلَّى قَالَ فَقُلْتُ لَهُ إِنَّ هَذِهِ لَصَلاَةٌ مَا كُنْتَ تُصَلِّيهَا . قَالَ إِنِّي بَعْدَ أَنْ تَوَضَّأْتُ لِصَلاَةِ الصُّبْحِ مَسِسْتُ فَرْجِي ثُمَّ نَسِيتُ أَنْ أَتَوَضَّأَ فَتَوَضَّأْتُ وَعُدْتُ لِصَلاَتِي .
Yahya related to me from Malik from Nafi that Salim ibn 'Abdullah
said, "I was with Abdullah ibn Umar on a journey and after the sun had
risen I saw him do wudu and then pray. So I said to him, 'This isn't a
prayer that you normally do. 'He said, 'After I had done wudu for the
subh prayer, I touched my genitals. Then I forgot to do wudu. So I did
wudu again and repeated my prayer.' "
