From the Hadith, Sahih Muslim, Book 17, Number 4206:
There came to him (the Holy Prophet) a woman from Ghamid and said: Allah's Messenger, I have committed adultery, so purify me. He (the Holy Prophet) turned her away. On the following day she said: Allah's Messenger, Why do you turn me away? Perhaps, you turn me away as you turned away Ma'iz. By Allah, I have become pregnant. He said: Well, if you insist upon it, then go away until you give birth to (the child). When she was delivered she came with the child (wrapped) in a rag and said: Here is the child whom I have given birth to. He said: Go away and suckle him until you wean him. When she had weaned him, she came to him (the Holy Prophet) with the child who was holding a piece of bread in his hand. She said: Allah's Apostle, here is he as I have weaned him and he eats food. He (the Holy Prophet) entrusted the child to one of the Muslims and then pronounced punishment. And she was put in a ditch up to her chest and he commanded people and they stoned her.
And from the Bible, John 8:3-11:
The teachers of the law and the Pharisees brought in a woman caught in adultery. They made her stand before the group and said to Jesus, "Teacher, this woman was caught in the act of adultery. In the Law Moses commanded us to stone such women. Now what do you say?" They were using this question as a trap, in order to have a basis for accusing him.
But Jesus bent down and started to write on the ground with his finger. When they kept on questioning him, he straightened up and said to them, "If any one of you is without sin, let him be the first to throw a stone at her." Again he stooped down and wrote on the ground.
At this, those who heard began to go away one at a time, the older ones first, until only Jesus was left, with the woman still standing there. Jesus straightened up and asked her, "Woman, where are they? Has no one condemned you?"
"No one, sir," she said.
"Then neither do I condemn you," Jesus declared. "Go now and leave your life of sin."
