Sahih
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 .
Yahya related to me from Malik from Ibn Shihab that Marwan ibn al-Hakam decided that if someone made three pronouncements of divorce, he had divorced his wife irrevocably. Malik said, "That is what I like best of what I have heard on the subject." 29.2 Divorce by Euphemistic Statements
