Muwatta Malik #1193
Marriage
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، أَنَّ خَوْلَةَ بِنْتَ حَكِيمٍ، دَخَلَتْ عَلَى عُمَرَ بْنِ الْخَطَّابِ فَقَالَتْ إِنَّ رَبِيعَةَ بْنَ أُمَيَّةَ اسْتَمْتَعَ بِامْرَأَةٍ فَحَمَلَتْ مِنْهُ . فَخَرَجَ عُمَرُ بْنُ الْخَطَّابِ فَزِعًا يَجُرُّ رِدَاءَهُ فَقَالَ هَذِهِ الْمُتْعَةُ وَلَوْ كُنْتُ تَقَدَّمْتُ فِيهَا لَرَجَمْتُ .
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! "
