It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that a man came to the service of the Prophet (peace and blessings of Allah be upon him) and said: O Messenger of Allah (peace and blessings of Allah be upon him)! By Allah! Ever since we irrigated the field after grafting the trees, I have not gone near my wife. The woman's husband had shins and arms, and his hair was straight, while the person with whom the woman was accused was extremely dark-skinned and had curly hair. On this occasion, the Prophet (peace and blessings of Allah be upon him) prayed, "O Allah! Make the reality clear," and had them perform li'an (mutual cursing), and the woman gave birth to a child resembling the person with whom she was accused.
