حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ رَبِيعَةَ بْنِ أَبِي عَبْدِ الرَّحْمَنِ، عَنْ مُحَمَّدِ بْنِ يَحْيَى بْنِ حَبَّانَ، عَنِ ابْنِ مُحَيْرِيزٍ، أَنَّهُ قَالَ دَخَلْتُ الْمَسْجِدَ فَرَأَيْتُ أَبَا سَعِيدٍ الْخُدْرِيَّ فَجَلَسْتُ إِلَيْهِ فَسَأَلْتُهُ عَنِ الْعَزْلِ، فَقَالَ أَبُو سَعِيدٍ الْخُدْرِيُّ خَرَجْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي غَزْوَةِ بَنِي الْمُصْطَلِقِ فَأَصَبْنَا سَبْيًا مِنْ سَبْىِ الْعَرَبِ فَاشْتَهَيْنَا النِّسَاءَ وَاشْتَدَّتْ عَلَيْنَا الْعُزْبَةُ وَأَحْبَبْنَا الْفِدَاءَ فَأَرَدْنَا أَنْ نَعْزِلَ فَقُلْنَا نَعْزِلُ وَرَسُولُ اللَّهِ صلى الله عليه وسلم بَيْنَ أَظْهُرِنَا قَبْلَ أَنْ نَسْأَلَهُ ‏.‏ فَسَأَلْنَاهُ عَنْ ذَلِكَ فَقَالَ ‏"‏ مَا عَلَيْكُمْ أَنْ لاَ تَفْعَلُوا مَا مِنْ نَسَمَةٍ كَائِنَةٍ إِلَى يَوْمِ الْقِيَامَةِ إِلاَّ وَهِيَ كَائِنَةٌ ‏"‏ ‏.‏

Yahya related to me from Malik from Rabia ibn Abi Abd ar-Rahmanfrom Muhammad ibn Yahya ibn Habban that Ibn Muhayriz said, "I wentinto the mosque and saw Abu Said al-Khudri and so I sat by him andasked him about coitus interruptus. Abu Said al-Khudri said, 'We wentout with the Messenger of Allah, may Allah bless him and grant himpeace, on the expedition to the Banu al-Mustaliq. We took some Arabsprisoner, and we desired the women as celibacy was hard for us. Wewanted the ransom, so we wanted to practise coitus interruptus. Wesaid, 'Shall we practise coitus interruptus while the Messenger ofAllah, may Allah bless him and grant him peace, is among us before weask him?' We asked him about that and he said, 'You don't have to notdo it. There is no self which is to come into existence up to the Dayof Rising but that it will come into existence.'
