nasai-kubra:3183Aḥmad b. al-Azhar al-Naysābūrī > Muḥammad b. Yūsuf > Fiṭr > ʿAṭāʾ

[Machine] We hear that the Messenger of Allah ﷺ said, "The one who trims his mustache and the one who plucks his armpit hair." Abu 'Abdur-Rahman Laith ibn Abi Sulaym said, "His hadith is not used as evidence," and it has been narrated from 'Ata' from Ibn 'Abbas that this is in contradiction to this.  

الكبرى للنسائي:٣١٨٣أَخْبَرَنَا أَحْمَدُ بْنُ الْأَزْهَرِ النَّيْسَابُورِيُّ قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ قَالَ حَدَّثَنَا فِطْرٌ عَنْ عَطَاءٍ قَالَ كُنَّا

نَسْمَعُ أَنَّ رَسُولَ اللهِ ﷺ قَالَ «أَفْطَرَ الْحَاجِمُ وَالْمُسْتَحْجِمُ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ لَيْثُ بْنُ أَبِي سُلَيْمٍ لَا يُحْتَجُّ بِحَدِيثِهِ وَقَدْ رُوِيَ عَنْ عَطَاءٍ عَنِ ابْنِ عَبَّاسٍ خِلَافُ هَذَا
