[Machine] The Messenger of Allah ﷺ said, "If one sits between the four corners [of the toilet] and strains, then ghusl (ritual bathing) becomes obligatory." Abu 'Abd al-Rahman said, "This is an error and we do not know of anyone who followed 'Isa ibn Yunus (may Allah be pleased with him). The correct narration is from Ash'ath from Al-Hasan from Abu Hurairah, and Al-Hasan did not hear from Abu Hurairah or did not hear this from Abu Hurairah." Abu 'Abd al-Rahman said, "I am uncertain."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «إِذَا قَعَدَ بَيْنَ شُعَبِهَا الْأَرْبَعِ ثُمَّ اجْتَهَدَ فَقَدْ وَجَبَ الْغُسْلُ» قَالَ أَبُو عَبْدُ الرَّحْمَنِ هَذَا خَطَأٌ وَلَا نَعْلَمُ أَحَدًا تَابَعَ عِيسَى بْنُ يُونُسَ عَلَيْهِ وَالصَّوَابُ أَشْعَثُ عَنِ الْحَسَنِ عَنْ أَبِي هُرَيْرَةَ وَالْحَسَنُ لَمْ يَسْمَعْ مِنْ أَبِي هُرَيْرَةَ أَوْ لَمْ يَسْمَعْهُ مِنْ أَبِي هُرَيْرَةَ قَالَ أَبُو عَبْدِ الرَّحْمَنِ أَنَا أَشُكُّ
