Arabic (Original)
حَدَّثَنَا الْفَضْلُ بْنُ دُكَيْنٍ حَدَّثَنَا سُفْيَانُ عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ سَمِعْتُ ابْنَ عُمَرَ قَالَ سَأَلَ عُمَرُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ تُصِيبُنِي الْجَنَابَةُ مِنْ اللَّيْلِ فَأَمَرَهُ أَنْ يَغْسِلَ ذَكَرَهُ وَيَتَوَضَّأَ وَيَرْقُدَ.
English Translation
al-Fadl b. Dukayn told us, Sufyan told us, from Abdullah b. Dinar: I heard Ibn Umar say: Umar asked the Messenger of Allah, peace and blessings be upon him, saying: "Sexual impurity befalls me during the night." So he instructed him to wash his private part, perform ablution, and then sleep.
