Mishkat al-Masabih #3057

He told of a man who went to God's Messenger and said, “I have a slave-girl who is our servant and I have intercourse with her, but do not want her to conceive.” He replied, “Withdraw your penis from her if you wish, for what is decreed for her will come to her.” After a time the man came and told him the girl had become pregnant, and he said, “I told you that what was decreed for her would come to her.” Muslim transmitted it.
