nasai-kubra:9981al-Faḍl b. Sahl al-Aʿraj > Muḥammad b. ʿAbdullāh al-Raqāshī > Jaʿfar b. Sulaymān > ʿAṭāʾ b. al-Sāʾib > Abū ʿAbd al-Raḥman > Ibn Masʿūd

[Machine] On the authority of the Prophet ﷺ , he said: "When any one of you sneezes, let him say, 'Alhamdulillah (praise be to Allah), Lord of all the worlds.' And it is said to him, 'May Allah have mercy on you.' When he hears that, let him say, 'Yaghfirullah (may Allah forgive you).' " Abu 'Abdur-Rahman said: "And this is a rejected hadith, and I do not consider Ja'far ibn Sulaiman to have heard it except from 'Ata ibn al-Sa'ib after they had mixed (with the innovators). 'Ata ibn al-Sa'ib entered Basra twice, and whoever heard it from him the first time, his hadith is authentic, and whoever heard it from him the second time, there is something in his hadith. And the hadith of Hammad ibn Zaid from him is authentic."  

الكبرى للنسائي:٩٩٨١أَخْبَرَنَا الْفَضْلُ بْنُ سَهْلٍ الْأَعْرَجُ قَالَ حَدَّثَنِي مُحَمَّدُ بْنُ عَبْدِ اللهِ الرَّقَاشِيُّ قَالَ حَدَّثَنَا جَعْفَرُ بْنُ سُلَيْمَانَ عَنْ عَطَاءِ بْنِ السَّائِبِ عَنْ أَبِي عَبْدِ الرَّحْمَنِ عَنِ ابْنِ مَسْعُودٍ

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا عَطَسَ أَحَدُكُمْ فَلْيَقُلِ الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ وَيُقَالُ لَهُ يَرْحَمُكُمُ اللهُ وَإِذَا قِيلَ لَهُ يَرْحَمُكُمُ اللهُ فَلْيَقُلْ يَغْفِرُ اللهُ لَكُمْ قَالَ أَبُو عَبْدِ الرَّحْمَنِ وَهَذَا حَدِيثٌ مُنْكَرٌ وَلَا أَرَى جَعْفَرَ بْنَ سُلَيْمَانَ إِلَّا سَمِعَهُ مِنْ عَطَاءِ بْنِ السَّائِبِ بَعْدَ الِاخْتِلَاطِ وَدَخَلَ عَطَاءُ بْنُ السَّائِبِ الْبَصْرَةَ مَرَّتَيْنِ فَمَنْ سَمِعَ مِنْهُ أَوَّلَ مَرَّةٍ فَحَدِيثُهُ صَحِيحٌ وَمَنْ سَمِعَ مِنْهُ آخِرَ مَرَّةٍ فَفِي حَدِيثِهِ شَيْءٌ وَحَمَّادُ بْنُ زَيْدٍ حَدِيثُهُ عَنْهُ صَحِيحٌ
