[Machine] The Messenger of Allah ﷺ said, "If it were not difficult for my nation, I would have made it obligatory for them to use the siwak (tooth stick) with every ablution, and I would have delayed the Isha prayer until half of the night." This is narrated by Abu Hurairah in this chapter, and they did not mention the word "obligatory" in it, and it is authentic according to both of them, and it has no defect. And it has a witness with this wording, as they did not mention the word "made obligatory," and it is according to their requirement and it has no defect.  

قَالَ رَسُولُ اللَّهِ ﷺ «لَوْلَا أَنْ أَشُقَّ عَلَى أُمَّتِي لَفَرَضْتُ عَلَيْهِمُ السِّوَاكَ مَعَ الْوُضُوءِ وَلَأَخَّرْتُ صَلَاةَ الْعِشَاءِ إِلَى نِصْفِ اللَّيْلِ» عَنْ أَبِي هُرَيْرَةَ فِي هَذَا الْبَابِ وَلَمْ يُخَرِّجَا لَفْظَ الْفَرْضِ فِيهِ وَهُوَ صَحِيحٌ عَلَى شَرْطِهِمَا جَمِيعًا وَلَيْسَ لَهُ عِلَّةٌ وَلَهُ شَاهِدٌ بِهَذَا اللَّفْظِ لم يخرجا لفظ فرضت وهو على شرطهما وليس له علة
