Hadith 3:163
‘A'isha said, “God’s messenger used to wash because of sexual defilement, then warm himself against me before I washed.” Ibn Majah transmitted it, and Tirmidhi transmitted something similar. In Sharh as-sunna it is given with the wording in al-Masabih .
وَعَنْ عَائِشَةَ قَالَتْ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَغْتَسِلُ مِنَ الْجَنَابَةِ ثُمَّ يَسْتَدْفِئُ بِي قَبْلَ أَنْ أَغْتَسِلَ. رَوَاهُ ابْنُ مَاجَه وروى التِّرْمِذِيّ نَحوه
