Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported that a man said: "O Messenger of Allah, I have a slave-girl, and I do coitus interruptus with her, fearing that she might conceive. I just want what men want. Meanwhile, the Jews say that coitus interruptus is minor infanticide." He said: "The Jews told a lie. If Allah intends to create it, you cannot prevent it."
This Hadīth refutes the Jewish claim that pregnancy is impossible with coitus interruptus in the sense that it is like the termination of procreation through infanticide. The Prophet (may Allah's peace and blessings be upon him) asserts that this a lie. He says that pregnancy, despite coitus interruptus, is possible. In this case, if Allah wants to create, He will, and vice versa. So coitus interruptus is not really infanticide. Therefore, the Prophet (may Allah's peace and blessings be upon him) allowed the Companion to do it and refuted the claim of the Jews.
