Narrated Ibn 'Abbas (RA):

Abu Rukana divorced Umm Rukana. So Allah's Messenger (ﷺ) told him, "Take your wife back." And he replied, "I have divorced her with three pronouncements." He said, "I have understood, take her back." [Reported by Abu Dawud].

وَعَنِ اِبْنِ عَبَّاسٍ ‏- رَضِيَ اَللَّهُ عَنْهُمَا‏- قَالَ : { طَلَّقَ أَبُو رُكَانَةَ أُمَّ رُكَانَةَ .‏ فَقَالَ لَهُ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-" رَاجِعِ امْرَأَتَكَ " , فَقَالَ : إِنِّي طَلَّقْتُهَا ثَلَاثًا.‏ قَالَ : " قَدْ عَلِمْتُ , رَاجِعْهَا } رَوَاهُ أَبُو دَاوُدَ [1]‏ .‏
