1. A number of our people have narrated from Ahmad ibn Muhammad from ibn Khalid from Muhammad ibn Ali from Hakam ibn Miskin from ‘ Ubayd ibn Zurarah who has said the following: “In our neighborhood there lived an old man who had a beautiful slave-girl for whom he had paid thirty thousand dirham; but he was not able to reach the satisfaction from her what he wanted and she would say, ‘Place your hand between my two flanges, I feel the pleasure’, but he did not like to do so. He asked Zurarah to ask abu ‘Abd Allah (a.s.), about it. Abu ‘Abd Allah (a.s.), said, ‘It is not unlawful, if he receives help from any part of his body to help her, but he must not seek help from what is other than his body to help her receive satisfaction.’”
