"The Messenger of Allah and I would take a bath from a single vessel."

The Messenger of Allah said: "When anyone of you wakes up from sleep, he should not put his hand into the vessel until he has washed it."

"The Messenger of Allah said: 'When anyone of oyu gets up from sleep and wants to perform ablution, he should not put his hand into the vessel he used for ablution until he has washed it, because he does not know where his hand spent the night or where he put it.'"

She asked the Messenger of Allah about a woman who sees in her dream that which a man sees. He said: "She does not have to take a bath unless she has an orgasm, just as man does not have to take a bath unless he has an orgasm."
