Musannaf Ibn Abi Shaybah 17490 — A man who wants to sell a slave girl

Abdullah bin Ubayd bin Umayr said: Sayyiduna Abd al-Rahman bin Awf (may Allah be pleased with him) sold a slave woman with whom he used to have intercourse, without making certain that her womb was empty. Pregnancy appeared in her while with the man who bought her, so he brought the case before Sayyiduna Umar (may Allah be pleased with him). Sayyiduna Umar asked Sayyiduna Abd al-Rahman: Did you use to have intercourse with her? He said: Yes. Sayyiduna Umar (may Allah be pleased with him) said: And you sold her without making certain that her womb was empty? He said: Yes. Sayyiduna Umar said: Doing so was not befitting of you. Then he called the physiognomists (qafah); they looked at the child and attached him to him.
