Hadith: O Messenger of Allah, may anyone of us sleep while being ritually impure? He said: Yes, he may sleep if he makes ablution

عَنِ ابْنِ عُمَرَ رضي الله عنهما:

أَنَّ عُمَرَ بْنَ الخَطَّابِ سَأَلَ رَسُولَ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ أَيَرْقُدُ أَحَدُنَا وَهُوَ جُنُبٌ؟ قَالَ: «نَعَمْ إِذَا تَوَضَّأَ أَحَدُكُمْ، فَلْيَرْقُدْ وَهُوَ جُنُبٌ».
[صحيح] - [متفق عليه] - [صحيح البخاري: 287]

‘Abdullāh ibn ‘Umar (may Allah be pleased with him) reported: ‘Umar ibn al-Khattāb (may Allah be pleased with him) said: "O Messenger of Allah, may anyone of us sleep while being ritually impure?" He said: "Yes, he may sleep if he makes ablution."
[Authentic hadith] - [Narrated by Bukhari & Muslim]

Explanation

‘Umar ibn al-Khattāb (may Allah be pleased with him) asked the Prophet (may Allah’s peace and blessings be upon him) about whether it is permissible for a man to sleep in a state of ritual impurity at the earlier part of the night, after having sexual intercourse with his wife, even if there is no ejaculation, or having a wet dream. The Prophet (may Allah’s peace and blessings be upon him) declared it permissible, provided that this major ritual impurity is lessened with ablution.
