حَدَّثَنَا يَحْيَى عَنْ سُفْيَانَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ دِينَارٍ سَمِعْتُ ابْنَ عُمَرَ قَالَ سَأَلَ عُمَرُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ تُصِيبُنِي الْجَنَابَةُ مِنْ اللَّيْلِ فَأَمَرَهُ أَنْ يَغْسِلَ ذَكَرَهُ وَلْيَتَوَضَّأْ
مسند امام احمد بن حنبل · Hadith 5190
'Abdullah ibn Dinar narrated: I heard Ibn Umar say: Umar asked the Messenger of Allah (PBUH): Sometimes I become janub at night. And he instructed him to wash his private part and do wudoo'.
