Abdullah bin Abbas reported,

He said that the matter of mutual cursing between spouses was mentioned in the presence of the Messenger of Allah ﷺ, and Asim bin Adi made a statement about it, then left.A man from his people met him and told him that he had found another man with his wife. Asim took him to the Messenger of Allah ﷺ, and he informed him of what he had found regarding his wife. The husband was a yellowish, thin man with straight hair, while the man he accused of being with his wife was dark-skinned, stocky, fleshy, with very curly, kinky hair.The Messenger of Allah ﷺ said, "O Allah, make it clear."She gave birth to a child resembling the man whom her husband said he had found with her, so the Messenger of Allah ﷺ had them perform the mutual cursing.A man in the gathering said to Ibn Abbas, "Is she the one about whom the Messenger of Allah ﷺ said, 'Had I stoned anyone without proof, I would have stoned this woman'?"Ibn Abbas replied, "No, that was a different woman who used to display wickedness openly in Islam."
