Muwatta Malik #108
Purity
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّهُ قَالَ ذَكَرَ عُمَرُ بْنُ الْخَطَّابِ لِرَسُولِ اللَّهِ صلى الله عليه وسلم أَنَّهُ يُصِيبُهُ جَنَابَةٌ مِنَ اللَّيْلِ فَقَالَ لَهُ رَسُولُ اللَّهِ
" تَوَضَّأْ وَاغْسِلْ ذَكَرَكَ ثُمَّ نَمْ " .
Yahya related to me from Malik from Abdullah ibn Dinar that
Abdullah ibn Umar related that Umar ibn al-Khattab mentioned to the
Messenger of Allah, may Allah bless him and grant him peace, that he
would sometimes become junub in the night. The Messenger of Allah, may
Allah bless him and grant him peace, said to him, "Do wudu and wash
your penis, and then sleep."
