"The Messenger of Allah swore to keep away from his wives and declared them as unlawful for him, so he made something permissible forbidden, and he offered expiation for having sworn to do so."
آلَى رَسُولُ اللَّهِ ﷺ مِنْ نِسَائِهِ وَحَرَّمَ فَجَعَلَ الْحَرَامَ حَلاَلاً وَجَعَلَ فِي الْيَمِينِ كَفَّارَةً
"The Messenger of Allah swore Ila from his wives, and he made something unlawful and he made himself unlawful what was lawful, and he made atonement for his oath."
آلَى رَسُولُ اللَّهِ ﷺ مِنْ نِسَائِهِ وَحَرَّمَ فَجَعَلَ الْحَرَامَ حَلاَلاً وَجَعَلَ فِي الْيَمِينِ كَفَّارَةً قَالَ وَفِي الْبَابِ عَنْ أَنَسٍ وَأَبِي مُوسَى
"The Messenger of Allah swore to keep away from his wives and declared them as unlawful for him, so he made something permissible forbidden, and he offered expiation for having sworn to do so." (Using translation from Ibn Mājah 2072)
«آلَى رَسُولُ اللَّهِ ﷺ مِنْ نِسَائِهِ فَجَعَلَ الْحَرَامَ حَلَالًا وَجَعَلَ فِي الْيَمِينِ كَفَّارَةً»
[Machine] The Messenger of Allah ﷺ forbade relations with his wives, and he made what is forbidden permissible. He made the right hand a means of atonement and there is strengthening in this for anyone who claims that the use of the word Haram (forbidden) should not be understood absolutely in terms of taking an oath, divorcing or showing disobedience.
آلَى رَسُولُ اللهِ ﷺ مِنْ نِسَائِهِ وَحَرَّمَ فَجَعَلَ الْحَرَامَ حَلَالًا وَجَعَلَ فِي الْيَمِينِ كَفَّارَةً وَفِي هَذَا تَقْوِيَةٌ لِمَنْ زَعَمَ أَنَّ لَفْظَ الْحَرَامِ لَا يَكُونُ بِإِطْلَاقِهِ يَمِينًا وَلَا طَلَاقًا وَلَا ظِهِارًا
