حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ قَالَ سَمِعْتُ ابْنَ عُمَرَ يَقُولُ سَأَلَ عُمَرُ رَضِيَ اللَّهُ عَنْهُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ تُصِيبُنِي الْجَنَابَةُ مِنْ اللَّيْلِ فَمَا أَصْنَعُ قَالَ اغْسِلْ ذَكَرَكَ ثُمَّ تَوَضَّأْ ثُمَّ ارْقُدْ
مسند امام احمد بن حنبل · Hadith 359
It was narrated that 'Abdullah bin Deenar said: I heard Ibn 'Umar say: 'Umar (RA) asked the Messenger of Allah (PBUH): If I become junub at night; what should I do? He said: "Wash your private part then do lottdoo' then go to sleep."
