The Jews used to sneeze in the presence of the Prophet ﷺ hoping that he would say: 'Yarhamukumullah (May Allah have mercy upon you).' So he said: 'Yahdikumullahu Wa Yuslihu Balakum (May Allah guide you and rectify your affairs).'"  

كَانَ الْيَهُودُ يَتَعَاطَسُونَ عِنْدَ النَّبِيِّ ﷺ يَرْجُونَ أَنْ يَقُولَ لَهُمْ يَرْحَمُكُمُ اللَّهُ فَيَقُولُ يَهْدِيكُمُ اللَّهُ وَيُصْلِحُ بَالَكُمْ وَفِي الْبَابِ عَنْ عَلِيٍّ وَأَبِي أَيُّوبَ وَسَالِمِ بْنِ عُبَيْدٍ وَعَبْدِ اللَّهِ بْنِ جَعْفَرٍ وَأَبِي هُرَيْرَةَ  

that he was with some people on a journey, and a man among the people sneezed and he said: "As-Salamu Alaikum (peace be upon you)." So he (Salim) said: "'Alaika Wa 'Ala Ummik (upon you and upon your mother)." It seemed as if that bothered the man, so he said: "Indeed I have not said except what the Prophet ﷺ said; a man sneezed in the presence of the Prophet ﷺ and said: 'As-Salamu 'Alaikum (peace be upon you)' so the Prophet ﷺ said: ''Alaika Wa 'Ala Ummik (upon you and upon your mother). When one of you sneezes let him say: "Al-Hamdulillahi Rabbil-'Alamin (All praise is due to the Lord of all that exists)" and let the one responding to him say: Yarhamukallah (May Allah have mercy upon you)" and let him reply: Yaghfirullah Li Walakum (May Allah forgive me and you both)."  

أَنَّهُ كَانَ مَعَ الْقَوْمِ فِي سَفَرٍ فَعَطَسَ رَجُلٌ مِنَ الْقَوْمِ فَقَالَ السَّلاَمُ عَلَيْكُمْ فَقَالَ عَلَيْكَ وَعَلَى أُمِّكَ فَكَأَنَّ الرَّجُلَ وَجِدَ فِي نَفْسِهِ فَقَالَ أَمَا إِنِّي لَمْ أَقُلْ إِلاَّ مَا قَالَ النَّبِيُّ ﷺ عَطَسَ رَجُلٌ عِنْدَ النَّبِيِّ ﷺ فَقَالَ السَّلاَمُ عَلَيْكُمْ فَقَالَ النَّبِيُّ ﷺ عَلَيْكَ وَعَلَى أُمِّكَ إِذَا عَطَسَ أَحَدُكُمْ فَلْيَقُلِ الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ وَلْيَقُلْ لَهُ مَنْ يَرُدُّ عَلَيْهِ يَرْحَمُكَ اللَّهُ وَلْيَقُلْ يَغْفِرُ اللَّهُ لَنَا وَلَكُمْ  

that the Messenger of Allah ﷺ said: "When one of you sneezes let him say: 'Al-Hamdulillahi 'Ala Kulli Hal (All praise is due to Allah in every circumstance).' And let the one replying to him say: "Yarhamukallah (May Allah have mercy upon you).' And let him say to him: 'Yahdikumullah Wa Yuslihu Balakum (May Allah guide you and rectify your affairs).'"  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا عَطَسَ أَحَدُكُمْ فَلْيَقُلِ الْحَمْدُ لِلَّهِ عَلَى كُلِّ حَالٍ وَلْيَقُلِ الَّذِي يَرُدُّ عَلَيْهِ يَرْحَمُكَ اللَّهُ وَلْيَقُلْ هُوَ يَهْدِيكُمُ اللَّهُ وَيُصْلِحُ بَالَكُمْ  

This is how Shu'bah reported this Hadith from IbnAbi Laila, and he said: "From Abu Ayyub from the Prophet ﷺ." Ibn Abi Laila was confused in this narration, sometimes he would say: "From Abu Ayyub from the Prophet ﷺ" and sometimes he would say: "From 'Ali from the Prophet ﷺ" similarly in meaning.  

عَنِ النَّبِيِّ ﷺ وَكَانَ ابْنُ أَبِي لَيْلَى يَضْطَرِبُ فِي هَذَا الْحَدِيثِ يَقُولُ أَحْيَانًا عَنْ أَبِي أَيُّوبَ عَنِ النَّبِيِّ ﷺ وَيَقُولُ أَحْيَانًا عَنْ عَلِيٍّ عَنِ النَّبِيِّ ﷺ  

(Another chain) from 'Ali from the Prophet ﷺ with similar meaning.  

عَنِ النَّبِيِّ ﷺ نَحْوَهُ
