Musannaf Ibn Abi Shaybah 17951 — Temporary marriage (mutah)

Sayyiduna Ibn Umar (may Allah be pleased with them both) was asked about mut'ah (temporary marriage), and he said that it is unlawful. It was said to him: "Sayyiduna Ibn Abbas (may Allah be pleased with them both) gives a fatwa permitting it." Sayyiduna Ibn Umar (may Allah be pleased with them both) said: "Then why did he not even murmur about it in the time of Sayyiduna Umar (may Allah be pleased with him)?"
