[Machine] The Prophet ﷺ made "khul'" a clear divorce that 'Abbad bin Kathir al-Basri distinguished himself with. Ahmad bin Hanbal, Yahya bin Ma'in, al-Bukhari, and Shu'bah bin al-Hajjaj spoke about it, and how it is valid. This is in opposition to the opinion of Ibn 'Abbas and 'Ikrimah, who considered it possible that the intended meaning is divorce when it is intended or mentioned. The purpose of it is to cut off the possibility of return, and Allah knows best.  

النَّبِيَّ ﷺ جَعَلَ الْخُلْعَ تَطْلِيقَةً بَائِنَةً تَفَرَّدَ بِهِ عَبَّادُ بْنُ كَثِيرٍ الْبَصْرِيُّ وَقَدْ ضَعَّفَهُ أَحْمَدُ بْنُ حَنْبَلٍ وَيَحْيَى بْنُ مَعِينٍ وَالْبُخَارِيُّ وَتَكَلَّمَ فِيهِ شُعْبَةُ بْنُ الْحَجَّاجِ وَكَيْفَ يَصِحُّ ذَلِكَ وَمَذْهَبُ ابْنِ عَبَّاسٍ وَعِكْرِمَةَ بِخِلَافِهِ عَلَى أَنَّهُ يَحْتَمِلُ أَنْ يَكُونَ الْمُرَادُ بِهِ إِذَا نَوَى بِهِ طَلَاقًا أَوْ ذَكَرَهُ وَالْمَقْصُودُ مِنْهُ قَطْعُ الرَّجْعَةِ وَاللهُ أَعْلَمُ
