I saw Abu Sa`id and asked him about coitus interruptus. Abu Sa`id said, “We went with Allah’s Apostle, 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 (ﷺ) (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.”
