Sahih Muslim 1438 a

I saw Abu Sa`id and asked him about coitus interruptus. Abu Sa`id said, "We went with Allah's Messenger (ﷺ) , in the Ghazwa of Bani Al-Mustaliq and we captured some of the 'Arabs as captives, and the long separation from our wives was pressing us hard and we wanted to practice coitus interruptus. We asked Allah's Messenger (whether it was permissible). He said, "It is better for you not to do so. No soul, (that which Allah has) destined to exist, up to the Day of Resurrection, but will definitely come, into existence."

I entered the Mosque and saw Abu Sa`id Al-Khudri and sat beside him and asked him about Al-Azl (i.e. coitus interruptus). Abu Sa`id said, "We went out with Allah's Messenger (ﷺ) for the Ghazwa of Banu Al-Mustaliq and we received captives from among the Arab captives and we desired women and celibacy became hard on us and we loved to do coitus interruptus. So when we intended to do coitus interrupt us, we said, 'How can we do coitus interruptus before asking Allah's Messenger (ﷺ) who is present among us?" We asked (him) about it and he said, 'It is better for you not to do so, for if any soul (till the Day of Resurrection) is predestined to exist, it will exist."

We got female captives in the war booty and we used to do coitus interruptus with them. So we asked Allah's Messenger (ﷺ) about it and he said, "Do you really do that?" repeating the question thrice, "There is no soul that is destined to exist but will come into existence, till the Day of Resurrection."

We took women captives, and we wanted to do 'azl with them. We then asked Allah's Messen- ger (ﷺ) about it, and he said to us: Verily you do it, verily you do it, verily you do it, but the soul which has to be born until the Day of judg- ment must be born.

Yahya related to me from Malik from Rabia ibn Abi Abd ar-Rahman from Muhammad ibn Yahya ibn Habban that Ibn Muhayriz said, "I went into the mosque and saw Abu Said al-Khudri and so I sat by him and asked him about coitus interruptus. Abu Said al-Khudri said, 'We went out with the Messenger of Allah, (ﷺ), on the expedition to the Banu al-Mustaliq. We took some Arabs prisoner, and we desired the women as celibacy was hard for us. We wanted the ransom, so we wanted to practise coitus interruptus. We said, 'Shall we practise coitus interruptus while the Messenger of Allah, (ﷺ), is among us before we ask him?' We asked him about that and he said, 'You don't have to not do it. There is no self which is to come into existence up to the Day of Rising but that it will come into existence.' "

Muhairiz said “I entered the mosque and saw Abu Sa’id Al Khudri . I sat with him and asked about withdrawing the penis (while having intercourse). Abu Sa’id said We went out with the Messenger of Allaah(ﷺ) on the expedition to Banu Al Mustaliq and took some Arab women captive and we desired the women for we were suffering from the absence of our wives and we wanted ransom, so we intended to withdraw the penis (while having intercourse with the slave women). But we asked ourselves “can we draw the penis when the Messenger of Allaah(ﷺ) is among us before asking him about it? So we asked him about it. He said “it does not matter if you do not do it, for very soul that is to be born up to the Day of Resurrection will be born.”
