"Two men sneezed in he presence of the Prophet ﷺ and he replied (said: YarhamukAllah; may Allah have mercy on you') to one and not to the other. It was said: 'O Messenger of Allah ﷺ, two men sneezed in your presence and you replied to one and not to the other?' He said: "'This one praised Allah(said Al-Hamdulillah fter sneezing) but that one did not.'"  

عَطَسَ رَجُلاَنِ عِنْدَ النَّبِيِّ ﷺ فَشَمَّتَ أَحَدَهُمَا أَوْ سَمَّتَ وَلَمْ يُشَمِّتِ الآخَرَ فَقِيلَ يَا رَسُولَ اللَّهِ عَطَسَ عِنْدَكَ رَجُلاَنِ فَشَمَّتَّ أَحَدَهُمَا وَلَمْ تُشَمِّتِ الآخَرَ فَقَالَ إِنَّ هَذَا حَمِدَ اللَّهَ وَإِنَّ هَذَا لَمْ يَحْمَدِ اللَّهَ  

"The Messenger of Allah ﷺ said: 'The one who sneezes may be responded to three times; if he sneezes more than that, he has a cold.'"  

قَالَ رَسُولُ اللَّهِ ﷺ يُشَمَّتُ الْعَاطِسُ ثَلاَثًا فَمَا زَادَ فَهُوَ مَزْكُومٌ  

"If anyone of you sneezes, let him say: Alhamdulillah (praise be to Allah). Those around him should respond by saying: Yarhamkullah (may Allah have mercy on you). And he should respond by saying: "Yahdikum Allah wa yuslaha balakum (may Allah Guide you and set right your state)."  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا عَطَسَ أَحَدُكُمْ فَلْيَقُلِ الْحَمْدُ لِلَّهِ وَلْيَرُدَّ عَلَيْهِ مَنْ حَوْلَهُ يَرْحَمُكَ اللَّهُ وَلْيَرُدَّ عَلَيْهِمْ يَهْدِيكُمُ اللَّهُ وَيُصْلِحُ بَالَكُمْ
