A man married a woman who had a daughter, and that man had a son from another woman. The son committed adultery with his stepsister. When Sayyiduna Umar (may Allah be pleased with him) came to Makkah, the matter was presented before him. He enforced the prescribed punishment (hadd) on both of them and tried to have them married, but the son refused.
