Arabic hadith text
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، أَنَّ مَرْوَانَ بْنَ الْحَكَمِ، كَانَ يَقْضِي فِي الَّذِي يُطَلِّقُ امْرَأَتَهُ الْبَتَّةَ أَنَّهَا ثَلاَثُ تَطْلِيقَاتٍ ‏.‏ قَالَ مَالِكٌ وَهَذَا أَحَبُّ مَا سَمِعْتُ إِلَىَّ فِي ذَلِكَ ‏.‏
Translation

Yahya related to me from Malik from Ibn Shihab that Marwan ibnal-Hakam decided that if someone made three pronouncements of divorce,he had divorced his wife irrevocably.

Malik said, "That iswhat I like best of what I have heard on the subject."
