Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) said: A man said: "O Messenger of Allah, I have a slave girl with whom I practise 'azl, for fear that she may become pregnant, and I want what men want; and the Jews say that 'azl is the minor burying alive." He (peace and blessings be upon him) said: "The Jews have lied. If Allah wills to create a soul, no one has the power to prevent it."
