Hilal ibn Yasar said: We were with Salim ibn Ubayd when a man from among the people sneezed and said: Peace be upon you. Salim said: And upon you and your mother. Later he said: Perhaps you found something (annoying) in what I said to you. He said: I wished you would not mention my mother with good or evil. He said: I have just said to you what the Messenger of Allah ﷺ said. We were in the presence of the Messenger of Allah ﷺ when a man from among the people sneezed, saying: Peace be upon you! The Messenger of Allah ﷺ said: And upon you and your mother. He then said: When one of you sneezes, he should praise Allah. He further mentioned some attributes (of Allah), saying: The one who is with him should say to him: Allah have mercy on you, and he should reply to them: Allah forgive us and you.  

سَالِمٌ وَعَلَيْكَ وَعَلَى أُمِّكَ ثُمَّ قَالَ بَعْدُ لَعَلَّكَ وَجَدْتَ مِمَّا قُلْتُ لَكَ قَالَ لَوَدِدْتُ أَنَّكَ لَمْ تَذْكُرْ أُمِّي بِخَيْرٍ وَلاَ بِشَرٍّ قَالَ إِنَّمَا قُلْتُ لَكَ كَمَا قَالَ رَسُولُ اللَّهِ ﷺ إِنَّا بَيْنَا نَحْنُ عِنْدَ رَسُولِ اللَّهِ ﷺ إِذْ عَطَسَ رَجُلٌ مِنَ الْقَوْمِ فَقَالَ السَّلاَمُ عَلَيْكُمْ فَقَالَ رَسُولُ اللَّهِ ﷺ وَعَلَيْكَ وَعَلَى أُمِّكَ ثُمَّ قَالَ إِذَا عَطَسَ أَحَدُكُمْ فَلْيَحْمَدِ اللَّهَ قَالَ فَذَكَرَ بَعْضَ الْمَحَامِدِ وَلْيَقُلْ لَهُ مَنْ عِنْدَهُ يَرْحَمُكَ اللَّهُ وَلْيَرُدَّ يَعْنِي عَلَيْهِمْ يَغْفِرُ اللَّهُ لَنَا وَلَكُمْ  

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  

" عَنْ هِلَال بْنِ يِسَافٍ قَالَ: كُنْتُ مَعَ سَالِمِ بْنِ عُبَيْدٍ فِى سَفَرٍ، فَعَطَسَ رَجُلٌ مِنَ القَوْمِ، فَقَالَ: السَّلَامُ عَلَيْكُمْ، فَقَالَ سَالِمُ بْنُ عُبَيْدٍ: عَلَيْكَ وَعَلَى أُمِّكَ، ثُمَّ قَالَ بَعْد: لَعَلَّكَ وَجَدْتَ مِمَّا قُلْتُ لَكَ؟ قَالَ: أَجَلْ! لَوَدِدْتُ أَنَّكَ لَمْ تَذْكُرْ أُمِّى بخَيْرٍ وَلَا بشَرٍّ، قَالَ: إِنَّما قُلْتُ لَكَ كَمَا قَالَ رَسُولُ الله ﷺ ، بَيْنَا نَحْنُ عِنْدَ رَسُولِ الله ﷺ إِذْ عَطَسَ رَجُلٌ فَقالَ: السَّلَامُ عَلَيْكُمْ، فَقَالَ النَّبِىُّ ﷺ : عَلَيْكَ وَعَلَى أُمِّكَ، ثُمَّ قَالَ: إِذَا عَطَسَ أَحَدُكُمْ فَلْيَقُلْ: الحَمْدُ لِلهِ رَبِّ العَالَمِينَ أَو الحَمْدُ لِلهِ عَلَى كُلِّ حَالٍ، وَلْيَقُلْ مَنْ عِنْدَهُ: يَرْحَمُكَ الله، وَلْيرُدَّ عَلَيْهِمْ يَغْفِرُ الله لَنَا وَلَكُمْ".
