Sahih al-Bukhari 5291
صحيح البخاري#5291Sahihوَقَالَ لِي إِسْمَاعِيلُ حَدَّثَنِي مَالِكٌ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، إِذَا مَضَتْ أَرْبَعَةُ أَشْهُرٍ يُوقَفُ حَتَّى يُطَلِّقَ، وَلاَ يَقَعُ عَلَيْهِ الطَّلاَقُ حَتَّى يُطَلِّقَ. وَيُذْكَرُ ذَلِكَ عَنْ عُثْمَانَ وَعَلِيٍّ وَأَبِي الدَّرْدَاءِ وَعَائِشَةَ وَاثْنَىْ عَشَرَ رَجُلاً مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم.
Ibn `Umar added:"When the period of four months has expired, the husband should be put in prison so that he should divorce his wife, but the divorce does not occur unless the husband himself declares it. This has been mentioned by `Uthman, `Ali, Abu Ad-Darda, `Aisha and twelve other companions of the Prophet (ﷺ)
Scholarly Authentication
The label above is the grade most of these scholars gave — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. Each scholar's own wording:
Every narration in Sahih al-Bukhari is accepted as Sahih (authentic) by the established status of the book.
