Sayyiduna Zayd bin Khalid al-Juhani (may Allah be pleased with him) said: On the day of Khaybar, a companion of mine and I were bargaining with a woman over the term of a mut'ah (temporary marriage), and we haggled at length. Then someone came to us and informed us that the Messenger of Allah (peace and blessings be upon him) had made the mut'ah marriage unlawful, and had made it unlawful to eat any predatory animal with fangs and the domestic donkey.
