Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates: I brought one of my slave girls and stood in the market of Banu Qaynuqa', so that I could sell this slave girl. A Jew came to me and said: O Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him)! Why is this girl here? I replied: Your children are present, so I said: I used to practice 'azl (withdrawal) with her. He said: This is a false oath of burying alive. I went to the service of the Noble Prophet (peace and blessings of Allah be upon him). I mentioned this to the Noble Prophet (peace and blessings of Allah be upon him). He (peace and blessings of Allah be upon him) said: "The Jews have said wrong, however, if you do not do so, there is no harm upon you."
