[Machine] Abu Bakr and Uthman, the sons of Abu Shaybah, narrated from Sufyan ibn 'Uyaynah, who narrated from 'Amr ibn Dinar, who narrated from 'Ata' ibn Abi Rabah, who narrated from Ibn Abbas, who said that the Messenger of Allah ﷺ said: "Do not defile your deceased, for a Muslim does not defile the living or the dead." This hadith is authentic according to the conditions of al-Bukhari and Muslim, but they did not include it in their collections.  

ثنا أَبُو بَكْرٍ وَعُثْمَانُ ابْنَا أَبِي شَيْبَةَ قَالَا ثنا سُفْيَانُ بْنُ عُيَيْنَةَ عَنْ عَمْرِو بْنِ دِينَارٍ عَنْ عَطَاءِ بْنِ أَبِي رَبَاحٍ عَنِ ابْنِ عَبَّاسٍ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ «لَا تُنَجِّسُوا مَوْتَاكُمْ فَإِنَّ الْمُسْلِمَ لَا يَنْجُسُ حَيًّا أَوْ مَيِّتًا» صَحِيحٌ عَلَى شَرْطِ الشَّيْخَيْنِ وَلَمْ يُخَرِّجَاهُ
