وَفِي لَفْظٍ لِأَحْمَدَ: «طَلَّقَ أَبُو رُكَانَةَ اِمْرَأَتَهُ فِي مَجْلِسٍ وَاحِدٍ ثَلَاثًا، فَحَزِنَ عَلَيْهَا، فَقَالَ لَهُ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -«فَإِنَّهَا وَاحِدَةٌ» وَفِي سَنَدِهَا اِبْنُ إِسْحَاقَ، وَفِيهِ مَقَالٌ»
Abu Rukana divorced his wife with three pronouncements, in one sitting. Then, he was grieved about her and the Messenger of Allah (sallallahu alayhi wa sallam) told him, “They (the three pronouncements) are reckoned as a single (utterance of divorce).”.
