Sahih al-Bukhari 5331

Narrated Al-Hasan:

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.

وَحَدَّثَنِي مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا عَبْدُ الأَعْلَى، حَدَّثَنَا سَعِيدٌ، عَنْ قَتَادَةَ، حَدَّثَنَا الْحَسَنُ، أَنَّ مَعْقِلَ بْنَ يَسَارٍ، كَانَتْ أُخْتُهُ تَحْتَ رَجُلٍ فَطَلَّقَهَا، ثُمَّ خَلَّى عَنْهَا حَتَّى انْقَضَتْ عِدَّتُهَا، ثُمَّ خَطَبَهَا فَحَمِيَ مَعْقِلٌ مِنَ ذَلِكَ أَنَفًا فَقَالَ 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 صلى الله عليه وسلم فَقَرَأَ عَلَيْهِ، فَتَرَكَ الْحَمِيَّةَ وَاسْتَقَادَ لأَمْرِ اللَّهِ‏.‏
