Mishkat al-Masabih, 459

‘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 <i>Sharh as-sunna</i> it is given with the wording in <i>al-Masabih</i>.

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
