that the Prophet Mohammad entered upon her, and he heard an effeminate man say to 'Abdullah bin Abu Umayyah: "If Allah enables you to conquer Ta'if tommorrow, I will show you a woman who comes in on four (rolls of fat) and goes out on eight." The Messenger of Allah said: "Throw them out of your houses." (FR)
