Mention was made about al-'azl in the presence of Messenger of Allah ﷺ, whereupon he said: Why any one of you practises it? (He did not say: One of you should not do it), for there is no created soul, whose creator is not Allah. (Using translation from Muslim 1438j)   

ذُكِرَ الْعَزْلُ عِنْدَ رَسُولِ اللهِ ﷺ فَقَالَ «لِمَ يَفْعَلُ أَحَدُكُمْ ذَلِكَ» وَلَمْ يَقُلْ «فَلَا يَفْعَلْ ذَلِكَ فَلَيْسَتْ نَفْسٌ مَخْلُوقَةٌ إِلَّا اللهُ خَالِقُهَا» اللَّفْظُ لِمُحَمَّدٍ  

[Machine] He heard Abu Sirmah and Abu Sa'id al-Khudri saying, "We captured some prisoners in the battle of Bani Mustaliq, which was the battle in which the Messenger of Allah ﷺ acquired Juhayriah. Amongst us were those who wanted to take them as slaves, and among us were those who wanted to enjoy themselves and sell them. So we consulted the Messenger of Allah ﷺ, and he said, "Let them be, for surely Allah has planned what will happen until the Day of Judgment."  

أَنَّهُ سَمِعَ أَبَا صِرْمَةَ وَأَبَا سَعِيدٍ الْخُدْرِيَّ يَقُولَانِ أَصَبْنَا سَبَايَا فِي غَزْوَةِ بَنِي الْمُصْطَلِقِ وَهِيَ الْغَزْوَةُ الَّتِي أَصَابَ فِيهَا رَسُولُ اللهِ ﷺ جُوَيْرِيَةَ فَكَانَ مِنَّا مَنْ يُرِيدُ أَنْ يَتَّخِذَ أَهْلًا وَمِنَّا مَنْ يُرِيدُ أَنْ يَسْتَمْتِعَ وَيَبِيعَ فَتَرَاجَعْنَا فِي الْعَزْلِ فَذَكَرْنَا ذَلِكَ لِرَسُولِ اللهِ ﷺ فَقَالَ «لَا عَلَيْكُمْ أَنْ لَا تَعْزِلُوا فَإِنَّ اللهَ قَدْ قَدَّرَ مَا هُوَ خَالِقٌ إِلَى يَوْمِ الْقِيَامَةِ»
