Ma'qil gave his sister in marriage and later her husband divorced her once.  

زَوَّجَ مَعْقِلٌ أُخْتَهُ فَطَلَّقَهَا تَطْلِيقَةً  

The sister of Ma'qil bin Yasar was married to a man and then that man divorced her and remained away from her till her period of the 'Iddah expired. Then he demanded for her hand in marriage, but Ma'qil got angry out of pride and haughtiness and said, "He kept away from her when he could still retain her, and now he demands her hand again?" So Ma'qil disagreed to remarry her to him. Then Allah revealed: 'When you have divorced women and they have fulfilled the term of their prescribed period, do not prevent them from marrying their (former) husbands.' (2.232) So the Prophet ﷺ sent for Ma'qil and recited to him (Allah's order) and consequently Ma'qil gave up his pride and haughtiness and yielded to Allah's order.  

خَلَّى عَنْهَا وَهْوَ يَقْدِرُ عَلَيْهَا ثُمَّ يَخْطُبُهَا فَحَالَ بَيْنَهُ وَبَيْنَهَا فَأَنْزَلَ اللَّهُ {وَإِذَا طَلَّقْتُمُ النِّسَاءَ فَبَلَغْنَ أَجَلَهُنَّ فَلاَ تَعْضُلُوهُنَّ} إِلَى آخِرِ الآيَةِ فَدَعَاهُ رَسُولُ اللَّهِ ﷺ فَقَرَأَ عَلَيْهِ فَتَرَكَ الْحَمِيَّةَ وَاسْتَقَادَ لأَمْرِ اللَّهِ  

Ibn ʿUmar bin Al-Khattab divorced his wife during her menses. Messenger of Allah ﷺ ordered him to take her back till she became clean, and when she got another period while she was with him, she should wait till she became clean again and only then, if he wanted to divorce her, he could do so before having sexual relations with her. And that is the period Allah has fixed for divorcing women. Whenever ʿAbdullah (bin ʿUmar) was asked about that, he would say to the questioner, "If you divorced her thrice, she is no longer lawful for you unless she marries another man (and the other man divorces her in his turn).' Ibn ʿUmar further said, 'Would that you (people) only give one or two divorces, because the Prophet ﷺ has ordered me so."  

أَنَّ ابْنَ عُمَرَ بْنِ الْخَطَّابِ ؓ طَلَّقَ امْرَأَةً لَهُ وَهْىَ حَائِضٌ تَطْلِيقَةً وَاحِدَةً فَأَمَرَهُ رَسُولُ اللَّهِ ﷺ أَنْ يُرَاجِعَهَا ثُمَّ يُمْسِكَهَا حَتَّى تَطْهُرَ ثُمَّ تَحِيضَ عِنْدَهُ حَيْضَةً أُخْرَى ثُمَّ يُمْهِلَهَا حَتَّى تَطْهُرَ مِنْ حَيْضِهَا فَإِنْ أَرَادَ أَنْ يُطَلِّقَهَا فَلْيُطَلِّقْهَا حِينَ تَطْهُرُ مِنْ قَبْلِ أَنْ يُجَامِعَهَا فَتِلْكَ الْعِدَّةُ الَّتِي أَمَرَ اللَّهُ أَنْ تُطَلَّقَ لَهَا النِّسَاءُ وَكَانَ عَبْدُ اللَّهِ إِذَا سُئِلَ عَنْ ذَلِكَ قَالَ لأَحَدِهِمْ إِنْ كُنْتَ طَلَّقْتَهَا ثَلاَثًا فَقَدْ حَرُمَتْ عَلَيْكَ حَتَّى تَنْكِحَ زَوْجًا غَيْرَهُ وَزَادَ فِيهِ غَيْرُهُ عَنِ اللَّيْثِ حَدَّثَنِي نَافِعٌ قَالَ ابْنُ عُمَرَ لَوْ طَلَّقْتَ مَرَّةً أَوْ مَرَّتَيْنِ فَإِنَّ النَّبِيَّ ﷺ أَمَرَنِي بِهَذَا
