صحيح ابن خزيمه
Sahih Ibn Khuzaymah
جماع أبواب فضول التطهير والاستحباب من غير إيجابChapters on Recommended Purifications
(174) بَابُ ذِكْرِ الدَّلِيلِ عَلَى أَنَّ الْأَمْرَ بِالْوُضُوءِ عِنْدَ إِرَادَةِ الْجِمَاعِ [أَمْرُ نَدْبٍ وَإِرْشَادٍ]،Chapter 174: Evidence that the command for ablution before intercourse is a recommendation
Hadith Q221
إِذِ الْمُتَوَضِّئُ بَعْدَ الْجِمَاعِ يَكُونُ أَنْشَطُ لِلْعَوْدَةِ إِلَى الْجِمَاعِ، لَا أَنَّ الْوُضُوءَ بَيْنَ الْجِمَاعَيْنِ وَاجِبٌ، وَلَا أَنَّ الْجِمَاعَ قَبْلَ الْوُضُوءِ وَبَعْدَ الْجِمَاعِ الْأَوَّلِ مَحْظُورٌ.
Because performing ablution after intercourse refreshes a person for intercourse again, not because it is obligatory to perform ablution between two acts of intercourse, nor because it is prohibited or unlawful to have intercourse again before performing ablution after the first intercourse.
