سنن النسائي

It was narrated that 'Abdullah bin 'Abbas said: "Mention of Li'an was made in the presence of the Messenger of Allah (ﷺ) and 'Asim bin 'Adiyy said something about that, then he went away. He was met by a man from among his people who told him that he had found a man with his wife. He took him to the Messenger of Allah (ﷺ) and told him of the situation in which he found his wife. That man was pale and slim with straight hair, and the one whom he claimed to have found with his wife was dark and well built, with very curly hair. The Messenger of Allah (ﷺ) said: 'O Allah, make it clear to me.' Then she gave birth to a child who resembled the one whom her husband said he had found with her. So the Messenger of Allah (ﷺ) conducted the procedure of Li'an between them." A man in the gathering said to Ibn 'Abbas: "Was she the one of whom the Messenger of Allah (ﷺ) said: 'If I were to have stoned anyone without evidence I would have stoned this one?'" Ibn 'Abbas said: "No, that was a woman who used to do mischief even after becoming Muslim."
