Yahya related to me from Malik from Ibn Shihab from Urwa ibn az-
Zubayr that Khawla ibn Hakim came to Umar ibn al-Khattab and said,
''Rabia ibn Umayya made a temporary marriage with a woman and she is
pregnant by him.'' Umar ibn al-Khattab went out in dismay dragging his
cloak, saying, "This temporary marriage, had I come across it, I would
have ordered stoning and done away with it! "
