Musnad Ahmad Hadith 19342

It is narrated from Zaid (may Allah be pleased with him) that when Ali (may Allah be pleased with him) was in Yemen, a woman was brought to him with whom three men had committed adultery during the same period of purity. He asked two of the men, "Do you acknowledge the child for this person?" They did not acknowledge. In the same way, he kept questioning each one together with the other until he completed this process, and none of them acknowledged the child. Then he cast lots among them, and the one whose name was drawn, the child was attributed to him, and two-thirds of the blood money was imposed upon him. This issue was presented before the Holy Prophet (ﷺ), and the Holy Prophet (ﷺ) said, "I also know the same solution that Ali has given."
